abstract = {Design reviews are a key bottleneck of fast product development processes. In order to judge manufacturability, reliable models of the design and the manufacturing process are essential. This paper presents a 2-D fluid simulation model as a manufacturability check for lead free mini wave soldering and evaluates it against soldering experiments. Miniwave soldering is a widely applied process to automatically solder THT-components onto mixed SMT/THT circuit board assemblies. The vertical hole fill is the acceptability criterion defined by the IPC-A610 and depends on the copper layer design of the THT solder joints due to thermal diffusion during the soldering process. With increasing copper content in high performance multilayer PCBs, the thermal diffusion increases likewise and causes significant soldering problems with respect to insufficient hole fill. To mitigate the design reviews as critical bottleneck for the time to market, in this paper a numerical 2-d model is implemented in ANSYS Fluent to predict hole fill of potential critical solder joints and validate the model against respective soldering experiments. The parametrized copper layer design of the solder joints are automatically generated by a python script, meshed and solved in ANSYS Fluent. This allows easy configuration of different copper layer designs with respect to board thickness, layer count and thickness as well as pin and hole diameter, solder nozzle diameter and the relevant soldering parameters. Temperaturedependent material models of the solder alloys to describe density, viscosity and wetting angle are derived from literature and applied to the simulation model. The simulation methodology is divided in two steps, first the flow field of the solder fontain has to be calculated. In the second step, the soldering process can be simulated based on the stable flow field including capillary action, heat and mass transfer based on the volume of fluid method. The simulation results show good agreement with soldering experiments. With this developed and validated simulation method the understanding of heat transfer and fluid mechanical effects during miniwave soldering can be improved.

abstract = {Electronic components are increasingly used in high-temperature environments like automotive and aerospace applications. For these applications, miniaturization is gaining importance so that traditional methods and materials encounter their limits. Therefore, with high thermal and chemical stability, ceramic materials offer an abundance of possible applications in the electronic circuit board sector. Furthermore, regarding miniaturization and increase of the functional density, electronic and mechanical components have to be merged. Reducing process time an alternative technology has to be found for applying a conductor track on a three-dimensional surface in little time.
This paper shows the whole production chain of the manufacturing of a three-dimensional mechatronic integrated device based on ceramics, beginning with the injection molding of different ceramic-based materials in four process steps: compounding, injection molding, two-step debinding and sintering.
For metallization of the ceramics, the paper presents an innovative plasma-coating technology. Thereby, a conductor track can be produced in only one process step within a few seconds without pre and post processing and without chemical substances. The system consists of two units: In one, the plasma generation module and the metal powder storage are hosted. In the other, the handling system and the plasma nozzle are located. In the plasma nozzle, the stream of carrier gas is ionized by an electric arc and is turned into a plasma state. The nozzle is fed with copper powder by two independent inert gas flows. Due to the high energetic plasma flame, the metal powder is melted and accelerated toward the surface of the substrate. A six-axis robot is used for handling the specimen and regulates the process speed, the distance between the nozzle and ceramic basic substrate as well as the applied layers to obtain the desired electrical and mechanical properties.
The paper also shows the influence of the most important parameters for the metallization process, which can be summarized in four main groups: the used substrate, the metal powder, the plasma generation and the handling. After that, different passivation materials are tested to protect the generated copper conductor tracks from corrosion and mechanical influences. Furthermore, the paper will describe the effects of using conductive adhesive and soldering paste for contacting electrical components on the plasma-coated surface.
The paper also presents investigations regarding the electrical resistance of the conductor tracks, the adhesive strength of the additively applied metal structures, and the maximum resistance to mechanical load before removing the electronic parts. The results of long-term tests deliver valuable information about the capabilities for a permanent use in automotive applications.
Due to the basic research, the paper will present different demonstrators, which will show various areas of applications. To show the advantages of ceramic materials, three-dimensional circuit carriers are exposed to extreme conditions like heat and chemicals. Due to the high temperature resistance, this technique can be used to build a temperature sensor, which can be installed near to hot engines or inside a battery for directly measurement of the temperature.},

abstract = {In this work we present the additive manufacturing of optical multimode waveguides on flexible foil by aerosol jet printing. In order to obtain higher aspect ratios for the waveguides, the foils are conditioned by a flexographic printing step in advance. This technique is used to manufacture asymmetric bus couplers, which allow for coupling without waveguide interruption. They follow the working principle of directional core-core-couplers but have different coupling ratios depending on the coupling direction, due to a bending of one of the coupling partners. The latest results on the printing process are shown, especially the laser structuring of the flexographic printing form to optimize the condition lines. Also the attenuation of the printed waveguides is measured as well as the coupling results of the asymmetric bus coupler. Especially the coupling powers and the strength of the asymmetric effect are shown 95% of their initial performance for >100 h. Complementary electroluminescence measurements reveal that the AJ-printed barrier layers effectively prevent lateral water ingress into the devices. Herein, the proof of principle is provided that AJ printing can be used to print barrier layers directly onto OEDs and is thus an industrially highly relevant technology to precisely encapsulate such devices even on 3D objects.},

abstract = {This article presents an innovative way for additive manufacturing of optical multimode waveguides for short range data transmission. By the use of aerosol jet printing between conditioning lines on flexible foils, low cost, and low weight polymer optical waveguides can be easily fabricated. The main advantages - compared to other waveguide manufacturing techniques - are the maximum fabricable waveguide length (not limited by panel- or wafer size), technology costs and 3D-ability. Furthermore, the printing allows for very long structures, which are not limited to wafer or panel sizes. In order to classify the new manufacturing approach and compare it to other technologies such as photolithography, imprinting, dispensing and ion-exchange, results on the mechanical (shear strength) and optical performance (transmittance, near field and attenuation) are presented. In addition, the experimental results on the data transmission performance are important to prove the suitability of the waveguides for high-speed communication applications. In this context, nearly error-free transmission up to 10 Gbit/s was achieved at a wavelength of 850 nm.},

abstract = {Dielectric elastomer actuators have been subject of researches in materials science since almost two decades. The synonymous denotation “artificial muscles” emphasizes the potential capability of those actuators, whereat the skeletal muscles of mammals, which are the biological archetypes, even are exceeded pertaining energy density and efficiency. These new kind of actuators depicts promising actuators for the development of a new generation of robotic solutions, such as inherently safe systems for human robot cooperation, highly dynamical, mobile and energy autarkic kinematics or even prosthetics. Since there are several challenges to be handled, like the high supply voltage, no automated manufacturing process for multilayered dielectric elastomer actuators is available and thus no actuators systems based on dielectric elastomer actuators for complex robot kinematics or commercial products. Now the Aerosol Jet Printing process seems suitable for an automated manufacturing process by printing such actuators and is investigated within the framework of the Bavarian biomimetic initiative “bionicum-forschung”. With this additive process stacked actuators are printed, where insulating and conducting layers are alternating and the automated manufacturing of stacked actuators with thousands of layers seems possible in the long term. With the new built actuators, new mobile and autarkic platforms in the range of a capuchin will be designed. Therefore lightweight power electronics are necessary, which investigation represents the second main research task within the project. Here only one high-mass central power supply is able to individually operate each of the artificial muscles on the platform with a pulse width modulated high voltage signal. Thus each actuator does not need its own supply. The presented project aims with the development of a mobile and autarkic platform the improvement of actual robot platforms regarding to dynamical int- ractions with the environment, like jumping, and the progress of the actual state of the art of robotics.},

abstract = {In this contribution we present recent findings of our efforts to qualify the so called Aerosol-Jet-Printing process as an additive manufacturing approach for stacked dielectric elastomer actuators (DEA). With the presented system we are able to print the two essential structural elements dielectric layer and electrode in one machine. The system is capable of generating RTV-2 silicone layers made of Wacker Elastosil P 7670. Therefore, two aerosol streams of both precursor components A and B are generated in parallel and mixed in one printing nozzle that is attached to a 4-axis kinematic. At maximum speed the printing of one circular Elastosil layer with a calculated thickness of 10 μm and a diameter of 1 cm takes 12 seconds while the process keeps stable for 4.5 hours allowing a quite high overall material output and the generation of numerous silicone layers. By adding a second printing nozzle and the infrastructure to generate a third aerosol, the system is also capable of printing inks with conductive particles in parallel to the silicone. We have printed a reduced graphene oxide (rGO) ink prepared in our lab to generate electrodes on VHB 4905, Elastosil foils and finally on Aerosol-Jet-Printed Elastosil layers. With rGO ink printed on Elastosil foil, layers with a 4-point measured sheet resistance as low as 4 kΩ can be realized leaving room for improving the electrode printing time, which at the moment is not as good as the quite good time-frame for printing the silicone layers. Up to now we have used the system to print a fully functional two-layer stacked DEA to demonstrate the principle of continuously 3D printing actuators.},

abstract = {A significant difference in the machinability of hard-to-machine materials can be observed among different batches of the same specified material. Thus, for cost-efficient machining, the ideal point of operation may vary for each batch. To investigate this, more than 1000 experiments at different cutting conditions with ten material batches are carried out. This data is used to train a support vector machine, capable of predicting a machinability index based on the material batch and the cutting conditions. The derived model is implemented as a cloud-based service, enabling its integration into a smart manufacturing assistant. It can be used for process optimization by predicting the machinability for given situations and, thus, finding the point of operation with favorable machinability.
Within recent years the gripping
and manipulation of individual objects using unmanned aerial vehicles
(UAVs) has become an area of broad scientific research as UAVs allow a
fast and three-dimensional transportation of the grasped objects.
However, currently there are neither standards for aerial gripping
devices nor are there grippers available that are both lightweight and
robust enough for the usage with drones and can provide the required
feedback on whether the gripping process was successful. In
this paper, we therefore present a lightweight, low-cost and
self-diagnosing mechatronic jaw gripper for the application with
autonomous UAVs. The gripper offers an energy-saving design and an
integrated measurement system to detect whether an object was
successfully grasped. To evaluate the performance of the gripper it is
attached to a quadrotor and tested within different scenarios. The tests
include the detection of successfully grasped or dropped out objects
and the autonomous pickup and deposit.

abstract = {The management and controlling of product costs play an important role in the early stages of value creation, since 70 - 80 % final product costs are determined in product development and design processes. Traditionally, the focus in business practice is often on the organizational controlling unit that records the corresponding costs when they occur. In those, later phases of the product lifecycle, the possibilities of exerting influence are very limited. Consequently, an accurate estimation of costs in the early design phase is an important instrument to support strategic decisions in the product engineering process. An intelligent approach based on machine learning to support cost management in the early design stage is presented. In a real-world case study using wheel cost data from a large original equipment manufacturer (OEM) we investigate the performance of a cross-validated machine learning framework using a greedy sequential forward feature selection method for dimensionality reduction, as well as grid search hyperparameter tuning in order to compare six regression algorithms. The results of the study show that it is possible to predict the costs of product components in the early design phase with an R2 of 0.960 using only seven features coming from the product design and development department. By a cluster analysis and scatter plots of prediction accuracies it is shown where the deviations in cost estimation come from. The study supports the statement that machine learning models are a promising instrument for product managers and cost engineers.
In this contribution, the authors suggest a methodology to predict the weight change of SMT components due to moisture absorption/desorption based on environmental conditions using a Machine Learning model. In this regard, one can decide for each component individually, if it needs to be dried based on the real amount of moisture absorbed and consequently, prevent the component failure in the production procedure. Temperature, humidity, and weight change of components are measured with the Magnetic Suspension Scale (MSC) and Thermogravimetric Analyzer (TGA) over time and under defined environmental conditions. To predict the weight change over a defined period, a Recurrent Neural Network has been trained which has shown a reasonable accuracy in predicting the weight change. Furthermore, to generalize the trained model for different types of components, parameters like dimensions and density are fed into the model to represent their physical characteristics. For the validation three different component types, classified for the Moisture-Sensitivity-Level 4 (MSL) are use},

abstract = {Robot-centric automation solutions (RAS) promise more efficiency and quality in production as well as more economic stability and security through local production, especially in the times of COVID-19. Nevertheless, due to their high complexity and costs, RAS are only used to a limited extent by small and medium-sized manufacturing companies. As a rule, the high costs of RAS arise from individual engineering, which takes up to 70 percent of the acquisition costs. For this reason, it is necessary to optimise the engineering of RAS. Among other things, better software and less costly top-down engineering methods are needed for this kind of enhancement. Pure optimisation via more advanced simulation tools is not sufficient. Configurators in particular offer the possibility of automatically arranging individual solutions from existing experience. Up to now, however, configurators have been used primarily for the individualisation of products, such as automobiles or clothing, on the basis of the variants predefined by the manufacturer, and less for the engineering of automation solutions. To make top-down configuration and simulation functions easily available to small medium enterprises, a web platform is a convenient solution. Due to the high complexity within the engineering domain, it is reasonable to build this kind of web platform with different services from specialised companies, e.g. by using microservices (MS). Conceivable roles could be as following. The web platform operator (WPO) offers an industry-specific, turnkey complete web platform. The WPO combines, integrates and orchestrates various modules and MS like configuration, simulation, data exchange and other. The MS can be provided by MS providers. In particular, since data interoperability and exchange are very important for engineering, an AutomationML (AML) MS is used to implement both. AML particularly supports the generic exchange of data based on industrial standards. To provide a general solution, a MS and AML-based web platform reference architecture was developed. These concepts and MS architecture are validated via a prototypical implementation and utilisation of the web platform within the scope of the ROBOTOP research project. Thus, the potential for increasing efficiency in engineering for RAS could be demonstrated using this top-down approach.},

However, present information systems do not allow flexible and reliable accumulation of high-dimensional data such as images and time series, so feature-rich data are often discarded in practice. The advent of edge computing and microservice-based software architectures in recent years enables low latencies, high data integrity, and flexibility towards different communication protocols, thus offering new possibilities to accumulate data in a manufacturing environment. Hence, this paper proposes a microservice architecture deployed on the edge that serves as a communication layer between data sources and downstream data analytics capabilities. The architecture's flexibility is demonstrated and validated on different process steps along the process chain of hairpin stator production. In conclusion, the developed microservice architecture is suitable for reliable data acquisition at the edge and can enable subsequent machine learning analyses across the process chain.},

abstract = {In today's complex supply networks, disruptions caused by diverse events represent major unknown operational conditions and risk factors requiring research on supply chain risk management. Hereby, operations management (OM) researchers are traditionally focusing on defining analytical and mathematical risk mitigation strategies characterized by a variety of different constraints, such as capacities, timeliness, or relations, leading to limited transferability into practice. Given the complexity of modern supply chains we argue that a data-driven approach to supply chain risk management enhances the assessment and comparability of risk mitigation strategies. Thereby an approach that allows conclusions about causal relationships between supply chain interventions and potential outcomes is of particular importance. Inspired by deep learning as well as causal learning theory and following a design science research approach, we design an analytical model that can predict supply disruptions based on external and internal data and quantify causal effects on delivery reliability. The model is evaluated in a single case study using data from a large first tier automotive supplier. The results show that the model has a high predictive performance and can learn causalities from observed data and analyze interventions effecting supply disruptions. The identification of causal relationships offers the potential to identify lacking supplier relationships and consequently bundle supply chain risk management activities. Building on the empirical and analytical insights, we discuss implications for both theory and practice.},

abstract = {LiDAR scanning is a widely-used method for accurately assessing roads and vehicular infrastructure. However, it can be costly and often overlooks infrastructure important for Vulnerable Road Users (VRU) like pedestrians and cyclists. Advances in electronics now permit high-performance LiDAR sensors made of standard semiconductor materials to be integrated into personal devices like smartphones and tablets. This study introduces a new classification category of handheld LiDAR systems for the purpose of VRU infrastructure mapping on a smaller scale. Qualitative experiments using a handheld LiDAR system were conducted to achieve low-cost mobile mapping of VRU infrastructure. The 3D Scanner App facilitated detailed and qualitative point cloud generation at low speeds. Moreover, it demonstrated precise detection of perpendicular potholes and bumps on roads. A quantitative analysis based on several infrastructure damages was performed, revealing mean average percentage errors of 3.53%, 4.43%, and 10.57% in the x-, y-, and z-directions, respectively. While the accuracy in the x- and y-directions is acceptable, the higher z-direction error indicates overestimation of infrastructural damage depth. In conclusion, the sensor's capabilities enable cost-effective mobile mapping solutions for VRU infrastructure monitoring, such as crowd-sourcing for urban data mining and urban digital twin interfaces, significantly reducing expenses compared to traditional sensors.},

abstract = {The implementation of sustainable production systems has been the focus of political, economic and social efforts for years. Due to the switch from fossil fuels to green energies, energy costs have been rising steadily for years. Energy-related taxes and levies can be reduced with a certified energy or environmental management system. ISO 50001 specifies requirements for the implementation of energy management system. Nevertheless, since 2017, ISO 50003 requires companies to demonstrate, by means of indicators, that energy efficiency is actually being continuously improved. Until now, only the proof, which shows that a systematic approach to reduce energy consumption is employed, was sufficient as a basis. However, the focus has now shifted towards the optimization of energy management systems. Nonetheless, these norms allow a wide scope for interpretation. This paper contains a methodology for the implementation of energy management system according to which companies can design there structure and processes to fulfil all the requirements specified in ISO 50001 and the other relevant energy management standards. The technical, business and organizational possibilities as well as the involvement of personnel along the McKinsey 7S model are considered. McKinsey's 7S change management tool provides the framework. The sustainable success of companies is analyzed using hard and soft factors. In this case, the model is applied to management systems.},

For both parties the establishment of an accurate cost estimation (CE) framework supports managing suppliers' costs as well as manufacturer's quotation costing. Grounded on resource dependence theory and following a design science research approach, this study introduces a multi-perspective CE system inspired by statistical learning, deep learning, decision making, and multi-agent theory. We evaluate our system by a single case and computer simulation study, using empirical data coming from observations and archives at a large Bavarian original equipment manufacturer (OEM). The results indicate that our CE approach allows to select the most significant cost-drivers and predict total costs of parts and assemblies with high accuracy. This supports the supplier in efficiently managing its costs. In making the CE blackbox model transparent using a combination of model agnostic post-hoc explainable artificial intelligence approaches we foster user acceptance for both suppliers and OEMs. All CE artifacts are ensembled in a multi-agent system to automatically manage costs with suppliers and furthermore, as a model extension, can lead to a collaborative price agreement.

Single organizations would, however, not aim at such a goal if it is to their economic detriment. GSCM research streams highlight that the successful implementation of environmental considerations leads to better economic performance in the long term. Therefore, this paper aims to identify and analyze suppliers that exhibit both environmental and economic success, indicating an effective and efficient realization of their sustainability measures. Given the long-term horizon of the research problem, we differentiate from previous microeconomic research by taking a macro perspective on sustainable supplier analysis, which investigates macroeconomic indicators focusing on firms' revenues. The above-described economic and environmental efficiency is analyzed in a multiple case study using sustainability reports from 66 OEM suppliers as well as data on their revenues and ratings on their carbon pollution measured by the Carbon Disclosure Project (CDP). First, a text mining inspired quantitative sustainable SWOT analysis is performed to evaluate the long-term strategy of organizations. A subsequent data envelopment analysis aims to identify efficient suppliers and causes for their efficiency. The overall results not only outline sustainable suppliers but also give insights into suppliers that may become sustainable in the future. We further show that large organizations struggle with meeting environmental expectations, whereas low-to-medium-sized suppliers tend to be more economically and environmentally efficient.

weight, power consumption, resolution and technology to acquire
3D-information resulting in different strengths and potentials.
Initially, we briefly explain our measurement setup, the
adjustable inputs and resulting outputs such as standard
deviation of depth values, precision and error rate. Afterwards
the results for each indicator, depending on camera sensors,
surfaces, and distances between object and camera will be
displayed. Based on our results, it is possible to quickly derive
optimal scene surroundings to improve the depth image of a
given 3D-camera before any programming effort is needed. A
more accurate depth image improves subsequent image
processing such as mapping, object or gesture tracking. This

With the ultimate goal of evaluating 100 % of solder joints of any given board, redundancy can occur regarding overlapping testing content. Whereas contemporary approaches to more efficient testing of electronic assemblies focus on the reduction of false calls using machine learning (ML), this paper analyzes the degree of redundancy between automated optical inspection (AOI) and X-ray inspection (AXI). We further explore possibilities for reducing the scope of testing to a necessary minimum, while still achieving full coverage of any given board. As communication of such analysis is of great importance in large-scale production facilities, a method of visualization is devised to utilize initial findings before a holistic approach can be implemented.

abstract = {In the fields of electronics manufacturing, the application of through-hole devices is still required, as heat dissipation and high current carrying capacity plays an important role. To ensure the highest quality standards, these electronics production processes take a multitude of inspection processes into account. For the detection of error patterns regarding the quality of the solder connections, usually, high-end inspection machines are utilized in the industrial application. The Automated Optical Inspection is a commonly conducted process, using visible light and rule-based inspection routines, setup by process experts for the evaluation of the Region of Interest. The high overhead of creating and maintaining product-specific checking routines and machine acquisition leads to increased costs and severe dependency on expert know-how. A flexible inspection algorithm, implemented into low-cost equipment for image generation is expected to reduce acquisition and optimization costs, and lower dependency on expert knowledge and high-end machinery. In this contribution, we present a novel framework for the automatic, near real-time solder joint classification based on Convolutional Neural Networks, flexibly detecting, and classifying solder connections. We utilize existing Deep Learning architectures for detection and classification. The localization model utilizes a YOLO-architecture (you-only-look-once), learning feature inputs based on a supervised learning approach. Pseudo-labeling is carried out automatically by an anomaly detection model. The image generation is executed by an industrial low-cost camera and an industrial rack-PC. The developed prototype is integrated into the existing production infrastructure. The results indicate a satisfactory detection and classification of the investigated solder connections with the proposed system. Hence, this system represent an alternative to commercially available high-end inspection systems being used for an inline control of Pin-in-Paste and through-hole device solder connections.},

Developments in the field of autonomous road traffic technology and the increasing availability of cost-efficient sensors allow the economic use of autonomous systems in various industrial sectors. One of the subareas of autonomous systems with economic and technological potential is the intralogistics material supply with driverless transport systems. While the usage between buildings of such systems is not yet economically feasible, development of cost-efficient sensors from other markets are opening up new approaches in this area of operation. Localization and navigation, which must work seamlessly in mixed indoor and outdoor usage scenarios, are particularly critical to the success of autonomous systems.
In this paper, a solution for the localization and navigation of autonomous driverless transport systems in a mixed indoor and outdoor scenario is proposed. It focuses on the use of cost-efficient sensors to enable a mostly infrastructure-independent localization of each system.

Purpose
Cost transparency is of central importance to reach a consensus between supply chain partners. The purpose of this paper is to contribute to the instrument of cost analysis which supports the link between buyers and suppliers.
Design/methodology/approach
Based on a detailed literature review in the area of cost analysis and purchasing, intelligent decision support systems for cost estimation are identified. Subsequently, expert interviews are conducted to determine the application possibilities for managers. The application potential is derived from the synthesis of motivation, identified applications and challenges in the industry. Management recommendations are to be derived by bringing together scientific and practical approaches in the industry.
Findings
On the one hand, the results of this study show that machine learning (ML) is a complex technology that poses many challenges for cost and purchasing managers. On the other hand, ML methods, especially in combination with expert knowledge and other analytical methods, offer immense added value for cost analysis in purchasing.
Originality/value
Digital transformation allows to facilitate the cost calculation process in purchasing decisions. In this context, the application of ML approaches has gained increased attention. While such approaches can lead to high cost reductions on the side of both suppliers and buyers, an intelligent cost analysis is very demanding.

abstract = {In electronics assembly, the convection based soldering technologies in the production lines consumes massive resources and energy. The recent advancements in soldering technologies consume comparatively higher resources and needs to be optimized for resource efficient production which is also the motivation for the present work. This study is devoted to quantify the resource consumption and qualify this consumption through exergy flows in an over-pressure reflow technology as an energy intensive process in electronics manufacturing. The analysis implies on a big saving potential for energy consumption specifically during the over-pressure process which also defines the void reduction quality of solder joints. Exergy efficiency is the fraction of the work potential of the heat that is converted to work, and it illustrates the quality of consumed resources during the soldering oven process. Shortening the production lead-time, and increasing the production rate increase the efficiency of exergy and prevents wastage of usable energy. Furthermore, the set-up improvements for the temperature profiles are necessary, and the changes toward developing new technologies in pre-heating and over-pressure chamber zones are mandatory if a high efficiency of resources used is expected.},

The reduction of the harmonic component in the fault current improves network stability and possibly prevents a blackout. A model has been simulated in Matlab-Simulink with multiple current sources working as compensation system in a 20 kV medium voltage example grid. The simulation results show that the harmonic distortion of the grid voltage has a significant influence on the magnitude of the fault current. That may lead to exceeding the extinguishing limit if the distortion is too high. With the presented method it is possible to significantly reduce the harmonic current without intervening the grounding of the transformer and the zero system. Furthermore, it is possible to place the system anywhere within the grid, which leads to a high degree of flexibility and facilitates upgrading.},

abstract = {Autonomous unmanned aircraft (UA) are currently gaining importance in various areas of application. In addition to their use in the field of surveying, inspection or fluid application, the focus is also on the transport of goods and the monitoring of factory premises. However, decisive disadvantage of commonly used UA is their short flight time, which typically ranges between approx. 10 and 45 minutes, depending on the design and payload. For the automated use of UA, it is not practical to manually change the battery between individual flights but automated solutions are required. The automated charging methods presented so far have in common that the UA approaches the landing platform vertically or at an angle from above and stands on the landing platform after completion. In this paper, we present a novel solution for the overhead charging of UA. Thereby the UA docks vertically to the charging station from below and is locked in the station. This saves floor space and allows the use of sensors attached to UA for information acquisition and environmental monitoring while charging. In addition to the charging station and the associated docking device attached to the UA, a camera-based method for localizing the charging station and for precise docking is presented. Finally, the docking and undocking process is evaluated in a series of experiments.},

abstract = {Establishing adequate cybersecurity for their operational technology (OT) is an existential challenge for manufacturing enterprises. Domain-specific security standards should provide essential support in this challenge. However, they cannot be implemented equally for enterprises of all sizes.We investigate to what extent domain-specific security standards for operational technology are applicable by small and medium-sized as well as large manufacturing enterprises, and how their individual need for action can be identified and addressed. We support our investigation with the results of two independent surveys among manufacturers about their needs for cybersecurity support.In the course of this investigation, we learned that most domain-specific security standards are well applicable to large enterprises. In contrast, small and medium-sized enterprises (SME) seek the support of security experts, who, for their part, are often struggling with a lack of experience in operational technology. To facilitate this cooperation, we provide an introduction for OT-and cybersecurity-experts to the respective basic concepts of their collaborators.},

A major cause is the lack of methodologies in this area. Production-related areas must be prepared to identify the requirements and needs of Industry 4.0, right from the planning phase of the project. This paper describes an approach to create an Industry 4.0 Project-Roadmap as a base of important strategical decisions. Using the VDMA industry 4.0 toolbox, innovative ideas are developed, structured and finally prioritized considering effort and costs. The result is a roadmap, which allows the design of basic Industry 4.0 equipment of the project as well as to integrate further features as options. Due to different target groups and a very specific expectation the workshop procedure is modified to the already by the VDMA published guideline and presented in detail below.},

Core of engineering activities is to accurately cover the requirements of the customer and design and build a perfectly fitting solution. Due to the one-time character of these projects, time and money can be saved by a reuse of knowledge from former projects as well as a strong methodology to execute these complex projects. The need for an efficient exchange of knowledge and further development of engineering methods (e.g. resource planning, training concepts, cross-country collaboration) has been recognized by many companies on a top level. At the same time there is currently no consistent approach, how to involve the experience of a broad engineering community in the development and implementation of efficient methods. This work describes an approach which closes the gap between a grown "community of practice" and a top-down initiative for the development of engineering methods and structured knowledge exchange. It ensures the deep involvement of experienced engineers from a vivid community for exchange and feedback. Three formerly described design principles (stakeholders, infrastructure, content and activities) of a community-based initiative have been applied to in a multi-sector engineering company.},

abstract = {The digitalization in manufacturing offers high potential for optimization in terms of quality and efficiency. In particular, machine learning techniques can be used to analyze data generated along the production chain for complex patterns. As the final product quality highly depends on interactions within the production chain, a process control system needs to consider all information of the supplied semi-finished products to achieve a continuously high quality. Using machine learning, this work presents a two-stage batch control system to optimize a batch process with high interdependencies between the delivered material, used equipment and process parameters concerning the final product quality.
This paper presents a measurement method
being capable of characterizing impact from sintering on
reached electrical conductivity of nano silver inks. Therefore,
a measurement setup at relatively low frequencies was chosen,
so that the electromagnetic (EM) field completely penetrates
the conductive region. Thus, the transmission which is highly
influenced by the conductivity variations of the material under
test can be measured. Even small variations due to different
sintering temperatures are measurable in this way. A model
describing the transmission of the EM-field through the material
sample including a carrier layer of polyimide was set up, which
allows for inferring the conductivity of the sample. As samples
sputtered copper layers are examined, as well as nano silver inks
sintered at different temperatures and with different sintering
methods.

abstract = {The rapid development of the Industrial Internet of Things (IIoT) has led to an explosion in the amount of data to be transmitted and stored in the industrial sector. The investigated images are used in particular for quality control after individual process steps as part of Automated Optical Inspections (AOI). Image processing systems are among the key technologies here. Nevertheless, the storage and transmission of image data is still a major challenge for many companies. The use of AI-based image compression methods with higher quality performance compared to conventional methods becomes inevitable. Convolutional Neural Networks (CNNs) or Transformers are currently gaining ground in this area. However, the efficiency of these architectures has not yet been demonstrated in an industrial scenario. In this work, both a CNN- and a Transformer-based model with built-in Attention Mechanisms are trained with 8 bits per pixel (BPP) grayscale images generated in an industrial ultrasonic sensor production line. Even in the first test phase, in which only 2,000 images were used for model training, a compression rate of 0.162 BPP is achieved, far exceeding the quality of comparable JPEG-compressed images. When training the models with 100,000 images, the lowest BPP rate of 0.009 is achieved by the Transformer-based algorithm, resulting in an image quality that is sufficient for most quality assessment use cases. Thus, our results demonstrate the applicability and superiority of AI-based compression algorithms in industry. Their use leads not only to more efficient data transmission, but also to huge savings in storage space and costs for companies compared to traditional image compression methods.},

abstract = {In condition monitoring of cutting inserts for machine tools, vision-based solutions enable detailed wear pattern analysis. Besides the main failure modes of flank wear and tool breakage, other defects, such as chipping, grooves, and build-up-edges, can be detected and quantified. However, manual analysis of the images is time consuming and traditional machine vision systems have limited capabilities adapting to changing situations, such as different insert types. As a result, robust machine learning techniques are researched to support the process of classifying images and detecting defects through image segmentation. For the latter, a variety of highly optimized networks exists. Still, these networks require tuning by machine learning experts. In contrast, automated machine learning is a recent trend that greatly reduces these efforts through automated network selection and hyperparameter optimization. In this study, automated machine learning is compared with manually trained segmentation networks on the example of tool condition monitoring. To achieve this, a heterogeneous dataset of over 200 industrial cutting tool images is recorded and evaluated. Comparing the manually trained segmentation networks to the automated machine learning framework, it is determined that the automated machine learning solution is easier to handle, faster to train and achieves better accuracies than other approaches.
The automotive value chain comprises a complex manufacturing network, which encompasses several departments, companies, and even countries. In the age of electrification and autonomous driving, the quality and transparency requirements are rising, in particular for electric and electronic components, which contribute to safety-critical functionalities. In this research, we analyze the traceability requirements and liability implications for the automotive manufacturing network. A key component in preventing safety and quality deficiencies in manufacturing processes is a state-of-the-art traceability system. Accordingly, we propose a blockchain-based traceability architecture to achieve the aspired level of transparency and process security. The proposed blockchain architecture processes manufacturing data entries and defines blockchain nodes, access, as well as consensus algorithm and transaction logic. An Ethereum-based blockchain demonstrator validates the architecture by implementing the logic for automotive product configuration and process sequencing based on the semi-fungible ERC 1155 token, the proof of authority consensus, and an automotive product token smart contract.

abstract = {Production processes are becoming increasingly complex and decentralized, spanning across multiple manufacturing areas, factories, and even countries. Thereby is the development of a holistic and data-continuous traceability system, which provides transparency of records for the entire manufacturing flow from raw materials to the final product, one of the main challenges. While some solutions already address traceability issues in supply chain management and manufacturing, customized and volatile industries, in which each product features a unique configuration, are still lacking appropriate models and proofs of concept. In this research, we develop a decentralized blockchain application called TokenTrail, which focuses on the specific traceability requirements of multi-hierarchical assembly structures. The proposed blockchain architecture is based on a consortium Ethereum network and a Proof of Authority consensus, which delivers a trusted and shared database within an economic processing framework. To overcome the challenges of managing liaison transformations, we develop an assembly token manager based on the semi-fungible ERC 1155 token, which enables a direct representation of complex assembly processes and structures containing unique parts and batches within one smart contract. A user-friendly front-end application simplifies the querying of the recorded traceability data and visualizes existing dependencies.
This paper proposes building blocks for digitally integrated process chains in the context of powder bed fusion (PBF) based AM to form a basis for transparency of cost and quality. Solving requirements for the end-to-end digital chain leads into challenges of acquiring, storing, processing and routing information.

The mapping of these enablers onto the AM chain leads to a target architecture that forms the fundament for future investigation},

abstract = {To monitor the carbon footprint of electric bus operations, this paper proposes a method to estimate the converted carbon emissions of electric buses based on the actual driving conditions. Taking the bus route 609 operating in the urban area of Xi'an City and the bus route 362 in the new built urban area as examples, based on real world driving data, a developmentscheme of localized driving cycles for urban electric bus operation lines is proposed. The T-distributed stochastic neighbor embedding (T-SNE) method is used for data dimensionality reduction. The Birch clustering method is used for classification, and then the driving cycles of the two study bus routes were constructed based on the principle of highest similarity and the ratio of each speed interval. The carbon emission is obtained through the conversion formula based on the power consumption calculated in cruise simulation environment. The results indicate that the electric bus routes 609 and 362 show obvious different energy consumption per 100 kilometers, which are respectively 121.71 kilowatt hourand 144.46 kilowatt hour. The result proves the necessity of constructing driving cycles for different bus routes. The carbon footprints of the routes 609 and 362 in November 2019 were also calculated based on the proposed method, which are respectively 114.099 ton and 117.863 ton. The proposed carbon footprint calculation method for electric bus is helpful for urban transportation carbon emission monitoring and management.},

abstract = {This article aims to explore the use and implementation of software-based production planning and control (PPC) systems in variant-rich manufacturing environments, specifically in the engineer-to-order (ETO) manufacturing. A systematic literature review is conducted to identify, which PPC tools are used in the ETO business, how they should be implemented and the benefits and challenges associated with their use. The results indicate that such systems can be technically and economically advantageous, however application of existing systems off-the shelf solutions is not recommended. The literature suggests a structured approach for the implementation considering critical success factors and a well-planned process supported by the proposed framework. Most of the systems analyzed in the literature are Enterprise Resource Planning systems. Furthermore, the findings show four different areas of positive effects for the companies, such as improved production efficiency, improved planning efficiency, improved decision-making, and increased competitiveness. Additionally, five different kinds of challenges can be observed: Knowledge and expertise, Cost and resource management, Process and system flexibility, Data management and IT infrastructure and System usability and applicability.
In an effort to meet climate protection targets, countries around the
world are promoting electro mobility. As a result of market growth, the
worldwide production capacities for electric motors for traction drives is
going to expand significantly. Besides, the existing technology must be adapted
to automotive-specific life cycle requirements. On the product side, the
electric machine has to reach maximum power densities in order to keep the
required limitations of space and weight. Furthermore, a fully automated
production process is essential to achieve high output rates and required
quality standards. The application of new adhesives and bonding processes
implements product-relevant properties in the production of components for
electric motors. Moreover, the selection of adhesive systems and process
parameters is crucial for cost-efficient and high quality manufacturing
processes in mass production. In the production of permanent magnet synchronous
machines, adhesives are used for joining of lamination stacks, fixation of
magnets and the overall assembling of stator housings.The paper analyses and evaluates different adhesive systems in terms of
their product and process capability using two cases of application. The
results serve as a starting point for further automated process development and
reveal the challenges of the adhesive application in production technology for
electric motors.},

abstract = {Especially in the production of electric drives, highly efficient drives in new use cases are needed to reach global climate targets. To obtain maximum motor power with minimal motor weight, it is necessary to fill the stator slots with a maximum of copper. In the past, the round wire has been the state of the art. However, with increasing efficiency expectations, round wires cannot reach the performance targets anymore. Form coils, also known as hairpins, are one common technology with higher fill factors. In addition, winding processes with endless flat or rectangle wires are currently in development and could fulfill the demand for electric drives in the future. Accompanied by new joining solutions, this technology could lower the production cost on the one hand and reduce the contacting spots with potentially increased contacting resistance on the other hand. One challenge in the automation of their winding and joining is a fully automated process chain, starting with the winding process and ending with end-of-line testing. One thing, all process steps have in common is the requirement to detect the position of the wires with high precision. This detection is fundamental to subsequent steps, performed by smart robot-based machines. lamination stack are considered.

are the resource-efficient production of stator and rotor sheet packages and the
reduction of iron losses during operation. The screen printing technology enables
the production of very thin magnetic sheet laminations in near net shape geometry

efficiency of electric motors in use will be increased by reduced eddy current and
hysteresis losses due to decreasing sheet thickness and avoided mechanical stress

components and variable alloy compositions. This paper presents the requirements
of the screen printing process for magnetic sheets and identifies the relevant influencing

abstract = {Electromagnetic actors (solenoids) are used in automotive and automation
technology as valve actors for pneumatics and hydraulics or as
actuating and pressure solenoids. During assembly there are often
press-in and caulking processes used. A central quality aspect of the
final control elements is the adherence to defined actuating force
ranges in order to ensure the switching process and at the same time to
keep wear within limits. These defined force ranges can currently only
be maintained by additional heat treatment of the parts. The hysteresis
of the assembled unit can be influenced by the caulking. The objective
of this paper is to propose the potential reduction of annealing
processes by revealing the interdependencies between the magnetic
interactions of the individual components and the assembly process
parameters. In addition, errors in the caulking process are detected and
prevented at an early stage. A magnetic characterization of the soft
magnetic components and assemblies before and during their assembly is
proposed. Furthermore, the integration of the measurement data into a
process control system is intended. The precondition is the development
and construction of measuring equipment and systems that can be used to
assess the magnetic properties at an early stage of assembly. The
assembly can then be adjusted in order to compensate batch fluctuations.
As a consequence new materials can be used to eliminate complex
annealing processes prior to assembly.

abstract = {Modern industrial production systems are facing the challenge of interconnecting and exploiting the increasing amount of data from smart products, software systems, and IIoT devices. One of the main tasks in this context is the implementation of a data-continuous traceability system, which interconnects the heterogeneous data objects over the entire production flow. While traceability maturity is already high in regulated and process-driven industries, the established traceability solutions cannot be successfully applied to customized and volatile industries. In this research, a graph-based traceability modeling methodology is presented that allows the systematic development of data continuity and integration in manufacturing. Based on the traceability methodology, the graph data model and architecture are specified, which are aligned to the requirements of customized and complex manufacturing systems. The model is implemented and validated based on a Neo4j graph database for the use case of the manufacturing process of automotive electrical systems. This research overcomes the shortcomings of state-of-the-art traceability models by shifting the focus to the relationships between traceability-relevant data objects. The proposed graph-based traceability model is able to capture multi-hierarchical product structures and is less dependent on physical object identification, making it more applicable to customized and complex manufacturing.
total industrial electricity consumption in Germany. As in electric energy systems based on renewable generation plants supply and demand often
do not occur in the same period of time, volatile prices occur and demand side management is gaining importance. Decentralized automation
offers opportunities in industrial environments for control of the equipment according to availability of electrical energy. Product-service systems
on industrial plants supply manufacturing equipment with compressed air, nitrogen and other technical gases, which partly can be obtained from
air by deposition processes. Those systems consist of air compressors, gas separators, reservoirs and lines. With suitable dimensioning and by
equipping with automation technology those product-service systems can be used for demand side management purpose. In addition to basic
operating parameters like current air pressure and status, those systems can process further information and create, for example, profiles on
compressed air consumption over time. By enriching those profiles with data on pressure, volumes, system restrictions and current production
requirements, the system control can identify the available potential for demand side management. Evaluation of operational strategies has to
optimize conflicting objectives within the triangular relationship of storage design, control of the production according to price prospects and

Dieses Denken in Wertschöpfungsnetzen wird in diesem Beitrag aus der Perspektive eines Maschinenlieferanten betrachtet und anhand unterschiedlicher Beispiele, die bereits im Markt beobachtbar sind, erläutert. Dieser Trend erfordert einerseits eine strategische Positionierung eines Maschinenlieferanten im Hinblick darauf, mit wem und in welcher Form er zukünftig firmenübergreifend zusammenarbeiten will. Andererseits erfordert dies auf der technischen Ebene eine firmeninterne Standardisierung der Informationsmodelle und Informationsflüsse über alle firmeninternen Wertschöpfungsprozesse hinweg, was wiederum eine geeignete technische Infrastruktur erfordert, die firmenintern aufgebaut und betrieben werden muss.
Digitization in engineering promises automated workflows, higher speed and lower costs in the development of automation solutions. The prerequisite for this is not only modularization based on a structured description language, but also uniform, interdependent modeling that ensures automated data exchange across system boundaries. In order to achieve a broad application, the underlying ontology should be based on existing norms and standards and be available in open source applications. However, the collaborative and consistent development of such an ontology requires a structured, methodical procedure and an associated modelling map that serves as an orientation for standardized, work-sharing modelling. A possible approach for the required procedure model and the related map will be presented in this article and validated using AutomationML. The presented approach should point out a possible direction and stimulate further process-controlled modelling efforts of ontologies.

Resource and energy efficiency of production facilities is a crucial competitive factor for industry. Due to increasing cost pressure and competition on the market, identifying and unleashing energy saving potentials as well as avoiding inefficiency is inevitable. However, for investment policy, the increase of energy efficiency is not always given highest priority. In this study we consider industry’s investment behavior for energy efficiency in relation to alternative production factors. For this purpose, this paper analyzes potential optimization issues and criteria that are taken into consideration for the decision making process for investments.

Instead of manually implementing complex standby strategies rigidly in a PLC, an intelligent system can train to derive decisions about the optimal energetic state of each component autonomously. Since learning in a virtual environment has decisive advantages, simulation models with sufficient accuracy are necessary. Many of the previous implementations of reinforcement learning approaches in an industrial environment are usually tailored to a specific plant. In particular, the agent's scope of action and its connection to the environment must be adapted manually for a new plant. The presented solution shows an intelligent system which automatically optimizes the virtual learning environment with the support of plant knowledge and adapts the reinforcement learning agent to the respective production plant.},

abstract = {Herkömmliche Industrieroboter müssen auf Grund ihres Gefährdungspotentials strikt von Bereichen, in denen Menschen arbeiten, getrennt werden. Die Programmierung ist bei komplexen Umgebungen aufwendig, sodass sich der Einsatz nur bei ausreichend hohen Stückzahlen lohnt. Auf Grund dessen werden Industrieroboter trotz der bekannten Vorteile gegenüber manueller Ausführung - wie Schnelligkeit, Ausdauer und Genauigkeit - in vielen Bereichen nicht eingesetzt, obwohl die Unterstützung von Produktionsmitarbeitern zur Vermeidung körperlich anstrengender und monotoner Aufgaben wünschenswert wäre. Dieser Beitrag stellt einen Ansatz für ein Roboterassistenzsystem vor, bei dem über eine 3D-Kamera basierte Arbeitsraumerfassung sowie manuell definierte Hindernisse ein aktuelles Umgebungsmodell generiert und automatisch eine kollisionsfreie Bahn für einen Sechsachs-Knickarmroboter errechnet wird. Dadurch kann der Einsatz von Robotern bei nicht vorhandenem Fachpersonal zur Umprogrammierung sowie bei kleineren Stückzahlen attraktiver werden. Es ergeben sich auch weitere Anwendungsgebiete für Industrieroboter, beispielsweise zur Unterstützung leistungsgewandelter oder geminderter Personen im Erwerbsleben. Eingangsparameter der automatischen Pfadgenerierung sind die aktuelle Istposition des Roboters und eine kartesische oder achsbasierte Zielposition. Eine hierarchische Zellzerlegung des Roboterarbeitsraums berechnet hierauf kollisionsfreie Zellen sowie mittels eines angepassten A*-Algorithmus den kürzesten Weg benachbarter, freier Zellen von der aktuellen Start- zur vorgegebenen Zielposition für den Werkzeug-arbeitspunkt (TCP, Tool-Center-Point) des Roboters. Es können sowohl synchrone Point-to-Point (PTP) als auch Linearbewegungen berücksichtigt werden. Die Orientierungsänderung zwischen Start- und Zielposition wird an die Wegänderung gekoppelt. Für alle Pfadstrecken zwischen den ermittelten kartesischen Stützpunkten wird in definierten Abständen eine hierarchische Kollisionsprüfung des Roboterarms mit der Umgebung durchgeführt. Hierfür werden bei Verwendung des PTP-Modus zunächst alle gültigen Konfigurationen der Stützpunkte und die sich daraus ergebenden, realisierbaren Kombinationen bestimmt. Falls Linearbewegungen erforderlich sind oder bevorzugt werden sollen, erfolgt zudem die überprüfung der Pfadabschnitte auf singuläre Stellungen, die zu einem Verwerfen der Bahn führen. Falls ein Stützpunkt oder ein Pfadabschnitt keine gültige Konfiguration liefert, wird ein künstliches Hindernis an der TCP-Position eingefügt und auf Basis des aktualisierten Arbeitsraummodells eine erneute Zellzerlegung und TCP-Pfadsuche angesto{ß}en. Um die notwendigen Kollisionsberechnungen zu beschleunigen, werden die Hindernisobjekte sowie der eingesetzte Roboter durch geometrisch einfache Hüllkörper umschlossen und überschneidungen mit dem Roboter hierarchisch geprüft. Neben der automatischen Bewegungsgenerierung wird im weiteren Verlauf dieses Beitrags als Erweiterung des beschriebenen Ansatzes auch die Möglichkeit einer Kollisionsüberwachung während der Roboterbewegung bei einem Einsatz ohne trennende Schutzeinrichtungen vorgestellt, sodass die Gefährdung von Menschen durch ein Anhalten des Roboters vermieden werden kann. Dabei werden auf Basis des aktuellen Arbeitsraummodells und der bekannten Roboteristposition hierarchische Abstandsprüfungen zu dynamischen Objekten und Personen durchgeführt und auf die Einhaltung eines angepassten Mindestsicherheitsabstandes geprüft.},

abstract = {Industrial communication technology often causes difficulties during planning and operation. For this reason, many planners still rely on wired communication technology because it is easier to plan and less susceptible to failures. The trend towards digitalization and Industry 4.0 can only be successfully implemented by making production more flexible. A pervasive flexi-bilisation can only be achieved by incorporating radio-based communication technologies and is therefore becoming more and more popular. Due to a lack of know-how in radio technologies, simulations can provide optimum support in planning. The earlier these simulations are used, the lower the error costs are due to timely correction. Since the manufacturer and type of communication components are not defined at such an early stage of planning, the communication requirements of applications and devices must be used to make an optimal approximation to the later real communication. This paper presents a type of co-simulation that suggests an optimal positioning of access points based on communication needs. Furthermore, the communication needs and their characteristics are presented.},

Strategic
change management is one of the crucial fields of cost analytics in the
automotive industry. Here, one important task is to explore potentials and
propose measures to reduce costs of parts in the product development process.
This is usually done within cost engineering and controlling departments of car
manufacturing companies. The costs of part modifications are analyzed and
specified usually by complex calculation methods based on a lot of input
parameters describing the properties of a specific part. The calculation
processes are mostly executed bottom-up. This means that the
cost of a part is determined by going through many attributes and assigning and
accumulating the corresponding cost estimations. These attributes comprise
features of CAD designs, built-in materials as well as production sequences.
That is why
the traditional calculation processes are effortful and time consuming. In
addition, they are predominantly carried out manually with the help of simple
calculation software like spreadsheets. Actually, Machine Learning (ML) algorithms
and models are occupying center stage to cope with this problem and make the
process more efficient. The overall goal is to predict costs of parts in the
early phase of the product development process. In this early phase the
expenditure of part modifications is low, but detailed information on the
structure of the part is scarce. Machine Learning models are expected to be
able to learn from a large amount of historical data and predict costs without
using bottom-up calculation formulas. Also, Machine Learning algorithms are
expected to find out the most influencing technical and economic parameters and
in this way are able to reduce the considered input data to factors that are at
hand in the early stage of the development process.
2 emissions of production systems. However, most components of the energy costs are determined during the very early phases of the product creation process. To achieve an estimation of the energy consumption in this early planning stage, a new suitable forecasting method is required. Therefore, this paper presents an approach for determining the prospective energy consumption by using Methods-Energy Measurement combined with defined energy reference cycles for manufacturing technologies. With this approach, key performance indicators are defined, and the production technologies are divided into basic energy consumers. The average energy values will be determined empirically by using the defined energy reference cycles. With these data, the energy demands for different scenarios are calculated. Thereby, it is possible to estimate the potential energy consumption of complex manufacturing cells. The designed method is validated within a case study of a modern automotive body shop. In summary, the approach contributes to identify and realize sustainable solutions in advance and thus increase the profitability of a factory.},

abstract = {Microservice (MS) architectures, especially in combination with micro front ends, are a modern, scalable and sustainable approach to software development. The modular development of individual components and the possibility of a simple, collaborative and iterative development represent a strategic advantage for companies. In addition, the MS approach allows the consistent use of current technologies, whereby new software functionalities can constantly be included. In this paper, the potentials of MS for engineering tools are shown using the example of a web-based configurator for robot-based automation solutions. On the one hand, the implemented prototype illustrates a possible MS architecture pattern and, on the other hand, clarifies how new functionalities such as the collaborative multi-user configuration or different role-based configuration sessions are enabled by such a concept. Using the example of the web-based configuration platform, it is finally shown how a MS architecture contributes to better development and easier deployment of engineering software solutions based on the divide and conquer principle.

In order to overcome these obstacles and to optimize the products' temperature curves the Institute for Factory Automation and Production Systems developed a simulative approach on the basis of the program Tecnomatix Plant Simulation. The implemented Temperature Module is hereby not only able to track a product's temperature through the whole simulated production chain.

abstract = {Small mobile ions, especially sodium and potassium are known to have the ability to infiltrate and move within gate oxide layers of silicon MOS devices. The ion transport in silicon oxide is either a temperature-driven, isotropic diffusion process, or an electrical ion current in presence of an electric field. Therefore, the high temperature gate bias test with negative polarity provides ideal conditions to identify the presence of mobile ions in the gate oxide of IGBT and MOSFET. Mobile ions in sufficient concentration can severely affect the electric characteristics, such as the turn-on and turn-off behavior of the MOS channel, by creating a shift in the gate threshold voltage or excessive sub-threshold currents. This paper shows several examples of how mobile ions can get into the gate oxide, e.g., via cracks in top side metallization, or by corrosive attack of cap layers. All these different failure modes develop the same electrical failure signature after temperature and/or gate bias stress. During the investigations on mobile ions, a special lock-in thermography method was developed that allows to localize the defect sites in the semiconductor by taking advantage of exclusive excitation of MOS cells affected by mobile ion contamination. Finally, after defect localization, further analytical methods can be applied to identify the exact nature of the access path to the gate oxide. Based on the test and analytical routine described above, a special test method was developed that allows to evaluate the permeability of the semiconductor chip top side structures towards mobile ions and to check for weak spots and potential leakage paths.},

abstract = {Laser direct structuring (LDS) is very important step in the MID process and it is a complex process due to different parameters, which influence on this process and its final product. Therefore, it is very important to use a reliable model to predict, analyze and control the performance of the (LDS) process and the quality of the final product. In this work we develop mathematical models by using Artificial Neural Network (ANN) and Response Surface Methodology (RSM) to study this process. The proposed models are used to study the effect of the LDS parameters on the groove dimensions (width and depth), lap dimensions (groove lap width and height) and finally the heat effective zone (interaction width), which are important to determine the line width/space in the MID products and the metallization profile after the metallization step. We also study the relationship between the LDS parameters and the surface roughness which is very important factor for the adhesion strength of MID structures. Moreover these models capable of finding a set of optimum LDS parameters that provide the required micro-channel dimensions with the best or the suitable surface roughness. A set of experimental tests are carried out to validate the developed ANN and the RSM models. It has been found that the predicted values for the proposal ANN and RSM models were closer to the experimental values, and the overall average absolute percentage errors were 4.02 % and 6.52%, respectively. Finally, it has been found that, the developed ANN model could be used to predict the response of the LDS process more accurately than RSM model.},

abstract = {So far, existing publications related to energy simulation of production systems predominantly focus on application or simulation aspects, with a particular emphasis on discrete event simulation (DES) of process chains. However, the modeling of energy aspects, even beyond the typical DES area, is crucial for a successful simulation project in terms of analyzing and optimizing energy-saving potentials within the industry. Therefore, this paper focuses on major techniques used to model the energy behavior of production systems across all levels of production systems, from individual components to a network of factories. Through a structured literature review, we identified the primary modeling techniques and typical characteristics for energy modeling and structured them in the form of a taxonomy.
system configuration and sizing of generation as well as storage technologies are essential steps for cost-efficient investments. In current research, flexibility options for electricity from growing renewable energies attract attention. One of the considered options is the power-to-gas technology in combination with fuel cells. Linear Programs for optimal system operation exist for example for distributed energy systems. In this study we propose a Mixed Integer Linear Program of a power-to-gas unit consisting of an electrolyzer, a fuel cell and a hydrogen storage. For the fuel cell a minimum load and a non-linear efficiency curve is taken into account. The non-linear efficiency curve is approximated by piecewise linearization. Bilinear products in the modeling of the efficiency curve are being substituted to maintain full power plant sizing and operation functionality. Different fuels, such as natural gas and hydrogen to be converted in the fuel cell, are implemented as well. As a result, we show that a detailed model of the non-linear efficiency curve of a fuel cell leads to more accurate results concerning the system operation. The configuration of system components in the observed energy system changes. Especially the battery system experiences a change in sizing and operation. However, solving time of the model is increasing dramatically. Our results demonstrate a valuable approach to compare the results of a Linear Program to a Mixed Integer Linear Program. Hence giving the possibility to evaluate the necessity of detailed over simplified models regarding calculation of cost-effectivenes},

abstract = {Current trends such as mass customization necessitate an agile and transformable production. In this context, robotic technologies are seen as a key enabler. But, to date, industrial robots lack the flexibility to easily adapt to changing needs. Therefore, a modular skill-based software framework aiming for free configurability is presented here. A generic task control allows varying incoming tasks to be processed, based on the actual skills of the robot. In this way, the flexible composition of a robot’s skills can be achieved, according to the actual situation. manufacturing of high precision ungrounded coplanar waveguides as high speed interconnections for flexible and wearable sensor as well as IoT systems. Characterization of these printed transmission lines up to a frequency of 24 GHz reveals an insertion loss of up to 8 dB/cm and therefore provides practical advice towards realizable line lengths. Although exhibiting approximately 4 times the attenuation as compared to conventionally manufactured flexible PCB transmission lines, the proposed approach allows for selectively realizing highly precise structures where necessary. Moreover, it is applicable on three-dimensional substrates, such as 3D-MIDs and therefore addresses various future applications.
Our research work has the goal to merge the advantages of ECAD and MCAD design instead of developing a completely new software environment. For that approach a layer model was generated, which connects the different software tools to
a holistic picture. This should fulfil all requirements in the collaboration of electrical and mechanical design. Also technical restrictions like design and manufacturing rules have to be considered. Due to the nature of 3D-MID not only the electrical functionality is focussed but also the dependence with mechanical conditions. E.g. mechanical contact faces shouldn’t be permitted for electronic part placement or the routing of tracks. In order to realize all these functions a platform independent product model is created and implemented to generate a connection between these different systems and the implicit user knowledge. This product model builds a base for the routing and placement task of 3D-MID and further additional modules that can be implemented into the software structure to improve the scope of functionality. Within the current project that focusses a semi-automated routing, the user will be allowed to rip-up connections between the parts and to reroute with customized conditions by setting waypoints on the carrier surface. The routing will be semi-automated what means that not all connections will be routed at once to allow the user to have several options for the track planning. Finally, future challenges will be evaluated and further use of the results will be discussed in the paper.

Nowaday, design and development of new materials with improved properties for 3D-MID are in focus. In this work, novel materials based on alumina ceramic with copper oxide additives are developed for this technology. The effect of the sintering temperature and the doping amount of copper oxide on the metallization quality is investigated. Furthermore, the influence of laser process parameters (e.g., laser power, velocity’, and frequency) on process output namely groove dimensions, groove profile, characteristics of structured area, and quality of the final 3D-MID products are discussed. The novel ceramic materials show high flexibility to realize very fine structures. Moreover, the laser-structured and metallized area shows a free edge lap with good quality. After metallization high accuracy with copper line/pitch of 16 μm/20 μm is achieved.},

abstract = {Stress urinary incontinence is a common pathologic condition in society and an increasing socio-economic challenge. Current artificial urinary sphincters for severe cases have high failure rates, cannot be applied sex-independent and their handling is not intuitive. To address these issues, a novel intraurethral closure system was developed. It works without an external energy supply and consists of an inflatable balloon that presses against the inner contour of a surrounding cylindrical structure implanted in the urethra. Regulation of the closure system is achieved by the interaction of the three main components: the closure balloon, the throttle and the compensating reservoir. The developed closing mechanism seals the bladder at rest and during short peak loads and opens only when the bladder pressure is increased by pressing with the abdominals for a longer period of time for micturition. Axisymmetric turbulent boundary layers that develop around streamwise
oriented long cylinder-like objects can be found in many applications,
such as towed array sonars or marine seismic streamers. In many of these
applications, turbulent fluctuations within the boundary layer flow can
have a negative impact compared with laminar flow conditions.
The aim of the present work is to design a surface modification that
influences the turbulent boundary layer around a cylinder in axial flow in order to reduce turbulent fluctuations. To design the surface we consider recent findings regarding the turbulence damping effects
of groove-like surface structures and combine these insights with the
effect of convex transverse curvature on turbulence. We use large-eddy
simulations to investigate the flow around a cylinder of modified design
and around a reference circular cylinder. Both flows have a
radius-based Reynolds number of Rea≈1.23⋅104" role="presentation">. The modified design leads to a 20 % decrease in the average wall shear stress and results in local reductions in the turbulent intensities, Reynolds stress, the temporal velocity spectrum, and the turbulent dissipation rate.
The analysis within the anisotropy-invariant space reveals a tendency
towards flow relaminarization. However, the new design has no effect on
turbulent pressure fluctuations. We provide suggestions on how to
further improve the surface design to achieve even greater flow
stabilizatio},

abstract = {Soft magnetic cores in electric machines conduct and enhance the magnetic flux. The magnetic properties of the single sheets are mainly influenced by the alloying elements, the microstructure and the rolling and annealing process. To reduce eddy current losses during operation, soft magnetic cores are laminated. However, all manufacturing processes and the further assembling steps, like mounting of the stator, change the magnetic properties of the stack. Laser welding is a common method for producing lamination stacks, as very thin sheets can be welded automatically with high velocities. However, the weld seams are electrically conductive connections, which lead to an increase in eddy current losses. Furthermore, the microstructure in the heat-affected zone is impaired, which leads to a higher demand for magnetization and increased hysteresis losses. A main reason for this is the magneto-mechanical effect, as mechanical stresses influence the magnetic properties. For improvement, the process parameters must be adapted to the specific material system and the requirements. In this paper, a numerical simulation model for visualizing and optimizing the heat distribution in welded electrical steel laminations is presented. The main objective is the analysis of the weld dimension for different welding parameters. For this purpose, a transient thermal analysis is carried out with Ansys Workbench. The welding process is mapped in a simplified way with a moving heat source for different conditions. To validate the results, a comparison to experimental tests is applied. In this way, the simulation results are verified and potential sources of errors are identified. },

Assistance systems capture information from the environment, process sensor data and provide the results to the impaired user. The paper presents an approach for efficient segmentation of obstacles in low-structured outdoor environments using encoder-decoder deep learning architectures and depth images. Therefore, an efficient method for generating training data using the v-disparity method is presented. Based on an extensive dataset of RGB and depth images and the corresponding binary label images, different state-of-the-art encoder-decoder architectures are evaluated on a mobile computing unit with respect to accuracy and efficiency. Besides pure depth-based architectures, RGB-D fused architectures are evaluated, too. The quantitative results show some limitations, but an additional qualitative evaluation proves the applicability of the approach to support the navigation of VIP by mapping the position of surrounding obstacles. Thus, an efficient combination of classical image processing, the integration of knowledge about the physical nature of the environment and deep learning can be made. Clinical Relevance- The approach supports the navigation of visually impaired people, which enables a more self-sufficient life related to higher quality of life.},

abstract = {Over the years, a complex spectrum of reliability testing was set up for electrical components. Necessary, but time- and cost-intensive qualification tests delay the development of new wiring harness components. Consequently, the acceleration of lifetime tests is of crucial importance for identifying and preventing damage mechanisms even before usage. Increased temperatures and relative movements both influence the tendency for fretting corrosion, which is the most relevant damage mechanism in receptacle contacts. This paper designs and constructs a test-setup that aims at introducing damage mechanisms in contacts. To replicate damage occurring during thermal shock testing, thermal and mechanical influences are separated by inducing relative movement between the electrical contacts. Fretting amplitudes taken from literature as well as simulations serve as a basis for the tested micro-movements. To investigate the occurring damage, laser scanning microscopy, an EDX spectrum and analysis of resistance progressions are carried out. The results show a clear correlation between the damage and the induced relative movements. Therefore, the presented test-setup provides realistic test-conditions for investigating degradation mechanisms of receptacle contacts. Further investigations provide the possibility of accelerating qualification investigations by higher fretting frequencies.
zeigt sich exemplarisch am Future Combat Air System, das ab ca. 2040 den Eurofighter ablösen soll. Für das sich in einem deutschfranzösisch-spanischen Entwicklungsprogramm befindliche Mehrzweckkampfflugzeug stellt KI eine Kernkomponente dar, ohne die die Operation und strategische Nutzung des Plattformsystems unmöglich wäre. Ähnliche Entwicklungen finden in den anderen Teilstreitkräften und Organisationsbereichen der Bundeswehr, insbesondere dem Cyber- und Informationsraum, statt. Der sichere Umgang mit und ein umfassendes Verständnis von KI werden daher für viele Soldaten und Soldatinnen eine essentielle Kernkompetenz. Um dieses Wissen nachhaltig zu vermitteln, findet KI zukünftig auch in kompetenzbasierten Lehr-/Lernformaten vermehrt Anwendung. Der vorliegende Beitrag mit der Methode eines systematischen Literatur-Reviews analysiert diese Entwicklung kritisch aus technologischer, organisationaler und didaktischer Perspektive. Neben einer Kategorisierung von KI-basierten (Aus-)Bildungsverfahren wird dabei besonderes Augenmerk daraufgelegt, inwieweit sich KI-Algorithmen, die in Ausbildung und Material zum Einsatz kommen sollen aber mitunter im Ausland entwickelt wurden, mit den Grundsätzen der inneren Führung, dem Leitbild des Staatsbürgers in Uniform sowie den Prämissen deutscher Sicherheitspolitik in Einklang bringen lassen. Als Ausblick wird das Konzept „künstlicher Ethik“ formuliert, das dem Einsatz von KI einen regulierenden Rahmen setzt.

abstract = {For the analysis of high-dimensional data in electromechanical manufacturing, data-driven techniques such as deep learning show great potential. However, the vast amount of required data poses a major barrier to the industrial adoption of said techniques. In the production of electric traction drives, this situation is further exacerbated by short innovation cycles. One of these innovations is hairpin technology, which is increasingly being employed by automotive manufacturers and suppliers. In contrast to classical deep learning approaches, few-shot learning aims at generalizing well despite limited data availability. This makes it ideal for the ramp-up phase of new production technologies for which no large legacy datasets exist yet. Therefore, this paper presents an empirical evaluation of few-shot learning techniques in the context of hairpin stator production. In doing so, we evaluate and benchmark several few-shot learning architectures and traditional approaches for quality monitoring of laser-welded hairpin windings based on image data.
Procurement decisions
are particularly affected by the digital transformation in many industries.
Purchasing, whose position shifts from pure procurement to value creation, has
to deal more and more with digital components. These digital components, by
their nature and economic characteristics, differ from conventional ones and
therefore rise the cost analysis of purchasing to new challenges. Many
companies are having great difficulties, especially with software, in verifying
the procurement costs of such components. Evaluation of software prices becomes
a more and more important part of cost engineering in companies. In theory and
scientific literature, a distinction is made in software evaluation procedures between
cost-, value- and license-oriented approaches. This paper presents the design
and results of an empirical study to find out which of these approaches are
currently being pursued and which ones are eyed for the future by companies in
different industries.

abstract = {Printed Electronics creates new areas of applications with a new manner of manufacturing electronics. Due to its technical and 3D design freedom, new markets and innovative products arise that were initially unthinkable. However, the focus of research is currently on mastering and improving the printing process. The subsequent process step of drying and densifying the printed structures to achieve high conductivities in the shortest possible time is up to now hardly considered. This paper treats the inquiry of fitted and optimized parameters of alternative promising photonic sintering methods for printed electronics compared to the much more time-intensive state of the art sintering process in a furnace. These photonic sintering methods comprise the near infrared, ultraviolet light as well as laser irradiation of the printed structures. Photonic sintering promises faster and more efficient curing and sintering due to the direct and selective application of energy to the printing structures without damaging the temperature-sensitive substrates. As substrate materials ABS and PC-ABS, as well as a glass material were used. Both polymer materials are standard and technical thermoplastics which are available at the market in huge quantities at low price. For the manufacture of printed circuits, a dispense printer was used, in order to process a low-cost silver-based micro particle paste. The evaluation of the sintering result was carried out based on the electrical conductivity of the printed conductor path and the adhesion strength on the substrate. In addition, the sintering time required for the curing of the structures as well as impacts on the substrate or the printed tracks due to photonic treatment were taken into account. To perform the experiments, two different print layouts were set up in order to be able to assess the electrical properties on the first layout and the adhesion on the second layout. To obtain a detailed statement on the exploration on the photonic sintering methods, a fully factorial design plan was conducted. For the near-infrared irradiation, the important parameters were the irradiation duration and the irradiation power. While sintered by ultraviolet light, the parameters were irradiation time, as well as the distance between the sample surface and the UV emitter. In the treatment by means of laser radiation, laser power and the motion speed were identified as the relevant parameters. In order to be able to draw a comparison to the mainly used sintering method, samples were also sintered in a furnace. The results show a significant reduction of the sintering time to a few seconds with comparable and even significantly better electrical and mechanical properties.},

abstract = {Machine Learning Operations (MLOps) enables the streamlining of the development and deployment processes of machine learning models; thus, manufacturers can utilize the inherent flexibility and adaptability of Deep Learning at scale to further optimize their processes. This publication provides insights into the challenges that companies face while striving for the efficient operationalization of machine learning algorithms. Moreover, a mapping of capabilities and requirements is presented to provide a baseline for the qualitative analysis of the current state of the art. In conclusion, this article discusses the shortcomings of the existing literature and provides novel implications for MLOps systems in manufacturing. 2 emissions. Therefore, a method for reducing the energy consumption of IR in manufacturing systems is desired. Firstly, this paper presents a literature survey of the research in energy consumption analysis of IR that is used in manufacturing processes. The survey found that current research in this field is focused on the development of simulation models of IR that are able to be used to predict its energy consumption. Secondly, a modular model to analyze power consumption and dynamic behavior of IR is developed. Afterward, an experimental investigation is carried out to validate and estimate the accuracy of the model developed. The investigation shows that the developed modular model can be conveniently used to optimize the industrial robot’s operating parameters, which are commonly needed for production planning and at the process optimization stage. In addition, the investigation shows that the process constraints, environment layout, productivity requirement, as well as the robot payload and operating speed are the key factors that must be considered for optimizing the productivity and efficiency of IR.},

abstract = {One of the major trends in the 21st century is the trend towards digital transformation within Industry 4.0. In order to adapt to high volatile market conditions, especially in the context of COVID-19, companies do not only have to transfer their knowledge into digital systems. Furthermore, they have to be able to tailor their business processes rapidly to changing customer’s needs. The implementation of efficient and transparent processes is thereby known as the process of digital transformation and requires its underlying software-architecture to be highly flexible and scalable. Especially a web-based platform represents a highly user-centered application for multi-user purposes and can quickly adapt to its customer needs. While e-commerce and video-streaming platforms, like eBay or Netflix, often already provide a highly flexible, microservice-based architecture, common tools and platforms within the engineering-domain are usually still based on rather monolithic or service-oriented architectures (SOA). Therefore, an adaption to changing market conditions and the integration of proprietary tools is often technically demanding and economically not feasible, especially for small and medium-sized enterprises (SME). In this context, the so-called Process-Driven-Approach (PDA) offers a sustainable and tool-neutral blue-print for a system’s architecture strictly following the separations-of-concerns principle and allowing a user-centered layout. The PDA enables the integration of business processes and tools within an orchestrating framework, provided by a process engine. While the PDA within the engineering domain has been presented in a preceding paper, this paper supposes a reference architecture and agile development method for engineering-platforms via the PDA based on the BPMN-standard and process engines. These concepts are validated by a prototypical implementation of a platform-demonstrator for tool-supported planning of robot-based automation solutions. Standard automotive power modules with sixpack topology and highest power density rely on metal ceramic substrates, direct liquid cooling by copper heat sinks and soft encapsulation by silicone gel. This study assesses the influence of novel thick copper substrates (TCS), with copper metallization thicknesses up to 2 mm, aluminium heat sinks and hard encapsulation by epoxy potting on the thermal performance and reliability of a power module package.
Soft potted power modules based on AMB substrates soldered onto a copper heat sink are compared to soft and hard potted TCS based modules on an aluminium heat sink.
Thermal impedances Zth j-f of all three mentioned module types are determined by FEM simulation and validated against impedance values measured during power cycling. TCS modules (Zth j-fFEM = 0.19) show better performance than AMB modules (Zth j-fFEM = 0.27).
Resistance of the solder interconnection between substrate and heat sink against thermo-mechanical stress is assessed by thermal shock tests. All modules types are therein able to meet the requirements set for the increase in thermal resistance within ECPE Guideline AQG 324. Differences between AMB and TCS delamination characteristics and the beneficial influence of hard potting onto solder delamination are investigated by scanning acoustic microscopy (SAM).
The thermal shock experiments are accompanied by thermo-mechanical simulations for additional quantification of AMB, TCS, heat sink and epoxy potting influence on the accumulation of plastic strain in the soldered substrate attach, as well as the sintered die attach layer.
Within the R&D-project VIRERO (VIrtual REmote RObotics for Radiometric Sorting, 10/2020 – 09/2023) a robot-based system for volume-optimized conditioning and testing is realized. The utilized disruptive robotic and radiological technologies enable efficient dismantling, handling and radiological waste sorting. Thereby, a spatially resolved radiological characterization is combined during image processing with complementary cameras. An augmented virtuality teleoperation provides the accurate simultaneous control of multiple robots through a single operator. For improved efficiency while maintaining high safety standards, the automated conditioning of highly individual waste and the relieve of operator workload are within the research scope of this projec},

Außerdem ermöglichen sie den Erhalt der Produktion in Deutschland. Die Automatisierung von manuellen Tätigkeiten gehört deshalb zunehmend zum Alltag in deutschen Unternehmen. Vor allem für kleinere Unternehmen ist allerdings der hohe Aufwand problematisch. Das Projekt ROBOTOP hat deshalb eine flexible Webplattform entwickelt, die es ermöglicht „baukastenartig“ Hardware-Komponenten zu individuellen Automatisierungslösungen zu kombinieren. Schlussbericht zu dem Teilvorhaben "Automatisierte Fertigungstechnologien zum Biegen, Montieren und Schalten von innovativen Formspulenwicklungen" im Verbundprojekt "PRO-E-Traktion" ("Automatisierte und robuste Produktionssysteme für E-Traktionsantriebe")
Gefördert durch das Bundesministerium für Wirtschaft und Technologie, begleitet durch DLR e. V. Projektträger
Förderkennzeichen: 01MX15011F
Die Formspulentechnologie gilt als Schlüssel zur Realisierung leistungsdichter elektrischer Traktionsantriebe. Darüber hinaus stellt sie eine Möglichkeit dar, die gegenwärtig schlecht kontrollierbaren Wickelverfahren durch stabilere Biege-, Montage- und Fügeprozesse zu ersetzen. Allerdings waren zum Zeitpunkt des Projektbeginns die benötigten Technologien weder identifiziert, noch entwickelt und qualifiziert. Hier setzt das vorliegende Projekt an, indem es technologische Alternativen für die durchzuführenden Prozessschritte identifiziert und priorisiert. Basierend darauf werden vollautomatisierte Prozessketten zur Herstellung von Statoren mit Hairpinwicklung in unterschiedlichen Stückzahlszenarien konzipiert und in Simulationen validiert. Um darüber hinaus Potentiale alternativer Arten offener Formspulenwicklungen bewerten und gegenüberstellen zu können wird eine Referenzmaschine auf diese übertragen und eine Bewertungssystematik entwickelt und angewandt, in deren Ergebnis die produkt- und fertigungsseitigen Potentiale von Hairpinwicklungen bestätigt werden. Die identifizierten Kernprozesse des Biegens, Montierens sowie der Kontaktierung werden grundlegend analysiert und auf dieser Grundlage die Industrialisierbarkeit der Prozesse abgeleitet. Für die Herstellung der Hairpins zeigt sich eine Kombination des Rotationszugbiegeverfahrens mit einem Gesenkbiegeverfahren als aussichtsreich. Zur Montage der Hairpins in den Stator werden unterschiedliche Konzepte ausgearbeitet und validiert, wobei die Wichtigkeit einer geeigneten Führung der Formspulen herausgearbeitet wurde. Es zeigt sich, dass der Kontaktierung eine wesentliche Rolle in der Prozesskette zukommt, wobei gezeigt wird, dass sich mit einer Kombination aus laserbasierten Isolationsabtrag und Laserstrahlschwei{ß}en ein geeigneter Kontaktierungsprozess ableiten lässt. Die erzielten Ergebnisse tragen zu einer Senkung der Hürde bei der vollautomatisierten Herstellung von Statoren mit Formspulen-wicklung bei, da sie die Technologieauswahl, Prozessentwicklung sowie Anlagenplanung maßgeblich vereinfachen
Bar-wound windings are regarded to be a key technology to realize electric traction drives with a high power density. Additionally, they provide an opportunity to replace recent winding technologies, that are characterized by a poor controllability, with bending, assembling and joining processes featuring a better process stability. Nevertheless, at the beginning of this project the technologies necessary were neither identified nor developed and qualified. To deal with these issues, the present project identifies and assesses technological alternatives for the process steps necessary. On that basis fully automated production chains for the production of stators with hairpin windings for different production volumes are designed and validated in simulations. Beyond that, the reference winding of this project is conveyed on alternative kinds of bar-wound windings. To be able to compare the resulting concepts, a rating system for bar-wound windings is developed that confirms the potentials of hairpin windings. The key process steps of bending, assembling and contacting identified in this project are analyzed fundamentally and based on these results, industrialization capabilities are derived. For the production of the hairpins, a combination of rotary draw bending and die bending proves to be promising. Different concepts to assemble the hairpins to the lamination are developed and analyzed. It is determined, that a suitable guidance of the bar-wound coil is necessary in any case. The analysis of the contacting process showed, that this process plays an important role in the process chain. Combining a laser based process for the removal of the insulation with a laser welding process is a suitable possibility to realize a reproducible contacting process. The results achieved contribute to a reduction of obstacles for the implementation of a fully automated production of stators with bar-wound windings, as they facilitate the selection of suitable technologies, the development of processes necessary and the planning of production facilities.

abstract = {From a theoretical perspective data does not constitute a traditional business asset. Existing valuation approaches are either sector specific or still unexplored. In modern businesses the value-adding use and monetization of existing “big data” represents one of the greatest potentials in the context of digital transformation. This paper aims at reviewing methods and developing an integrated methodology for the value determination of data in general and for use in the manufacturing industry in particular. Therefore, the general state of research in data value assessment is investigated by a broad literature analysis. Based on the identified general principles, methodological requirements for data value determination are compiled. A new methodology for data evaluation is developed and applied to four use cases coming from the automotive industry. The results show that the methodology can be used in different contexts and thus enables managers to explore the most promising use cases for data-driven business.

abstract = {The term Virtual Reality (VR), is very well known in the consumer goods and entertainment sector. The visual presentation of the VR environment is typically achieved via stereoscopic head-mounted displays (HMD), and the interaction via a 3D position detection of HMD and additional input devices such as controllers for active user input. While the variety of applications in the entertainment industry is constantly growing and the technological possibilities become more extensive, this trend has marginally established itself in the industry. Even though powerful and affordable VR hardware is available, VR applications are often associated more with gaming than professional industrial applications. In addition, only few interaction mechanisms such as 3D viewing, moving, teleporting and rarely direct interaction capabilities are used in the most industrial VR solutions. The reason for this is often a lack of understanding and structure of use cases and the added value that VR applications and interactions create for companies and their customers. This unnecessarily limits the applicability of new VR applications for the industry. For a better structuring of VR use cases and required 3D objects for targeted user interaction, we introduce seven Levels of Detail. Along these, one VR use case setup is created, to provide examples for classical concept planning and a new knowledge-based process based on engineering Best Practices. For each, we derive adequate prototypical implemented demonstrator stations and necessary interaction mechanisms for VR development. To highlight further VR possibilities, we extend the examples by adding a second use case setup for VR planning and virtual commissioning of industrial human-robot collaboration solutions based on body and hand tracking. Hence, the contribution provides a structured compilation of potential and useful industrial VR planning use case setups and for these relevant interaction mechanisms in combination with concretely implemented examples.},

abstract = {Digital human models have not yet reached their full potential for
proactive virtual assessment of ergonomics in engineering and industrial
design. Especially the modelling of interaction between user and
product often is time demanding, cumbersome, unstandardized and embedded
insufficiently in the computer-aided engineering environment. On the
one hand, the interaction modelling needs to be applicable for a
majority of products and shall contain as much a-priori knowledge
regarding human behavior as possible. On the other hand, the method
needs to be appropriate for designers, without special ergonomic
expertise or human behavior training. In this contribution, we present
an interaction-modelling framework based on the concept of affordances,
which ought to resolve these partly contradictable demands. Hence, 31
elementary affordances, describing fundamental physical interaction
possibilities between human end effectors and rudimental (product)
geometries, were deduced using a classification method. The elementary
affordances shall serve as a medium for interaction modeling. For this
purpose, we introduce an interaction modelling routine, implemented in a
CAD system, which makes use of the identified elementary affordances in
terms of CAD-features. Those enable designers to apply interaction
possibilities directly to a CAD-model in order to define the constraints
for a DHM simulatio},

abstract = {High power LEDs have become increasingly important for industrial applications due to their long life-cycle and high energy saving potential. To achieve the maximum efficiency and lifetime, the quality and stability of the LED packages must be ensured. A critical factor is the reliability of the solder joints, especially with lead-free solder alloys because of the process-induced voids during the soldering process and consequent failure mechanisms during service. This contribution focuses on the influence of the voids on the reliability of solder joints for high-power LED applications. Concerning the long time scale for the reliability tests such as temperature shock tests (TST) or power cycling tests (PCT), finite-element-method had been considered to enable a simulation-aided analysis and to gain a better understanding of the fatigue behavior of the solder joint with different voids distributions. In the simulation, all the models are based on the real experiments with produced test assemblies with high and low voiding levels. The test assemblies were characterized before and after the reliability tests by using computer tomography (CT) in order to document the crack initiation. Based on the measured dimensions of the solder joints, 3D-models were built with different sizes and positions of voids. For the material behaviors, the Garofalo equation is implemented for calculating the creep strain and to detect the crack initiation. Various test conditions (for TST and PCT) have also been taken account of in order to reduce the deviation between reality and simulation. Finally, the simulated results of crack initiation are compared with the results of real experimental data. The Comparison shows good correlation between simulations and experimental tests with respect to failure modes such as the position of cracks. Potentials and challenges of using numerical methods are also discussed for further studies.},

abstract = {The molded interconnected devices (MID) technology is vastly growing as an important innovative technology in the field of electronics production. The laser direct structuring (LDS) method is one of the most common available technologies for building up MID’s products. The current existing knowledge in industry and in research about the standards in the respective manufacturing processes and process parameters is up to now not fully comprehensive in terms of mutual influencing and dependencies on each other. This is particularly the case for the three-dimensional applications and micro products. In the present contribution, a new simulation procedures based on a three-dimensional finite element model (FEM) has been developed. The effect of each of latent heat of fusion and temperature on the material properties as well as the 3D Gaussian heat source for the laser beam has been considered in this work. The used material was a polymer plate poly ether ether ketone (PEEK). The effect of the process parameters including laser power, speed, frequency, hatching percent or overlap between the laser lines, the laser incident angle, and the focal length have been investigated in experiments and simulations. The present simulation can be used to predict, temperature distribution, maximum temperature, groove dimensions, and groove profile at different process parameters setup. The theoretical and the experimental results can show a good accordance. It can be concluded that the FEM simulation can be used efficiently for predicating, analyzing, and optimizing the 2D/3D laser parameters for the LDS process.},

The most energy consuming process step is the autoclaving. About 87% of the energy is required for this particular process step, where the green bodies are steam-hardened at 200°C.For reducing the energy consumption, most of the alternatives aim at optimizing the complete manufacturing process. In this paper, the focus is put on an optimized loading process for the autoclaves, in consideration of preceding and subsequent process steps. For this purpose, a simulation model is developed, where different strategies of loading are implemented and tested. This model can be used to find optimally scheduled assignments of production orders to the available autoclaves, based on the volume of each manufactured product.The analysis of the tested strategies shows, that it is possible to save up to almost 9 % of the required energy for autoclaving by an optimized assignment of the available autoclaves.},

abstract = {The use of electric power systems in automobiles represents a massive change in the production line of car manufacturers. To guarantee an efficient and at the same time damage free installation of the current carrying high-voltage cables, virtual validation of assembly operations makes an important contribution. On the market available simulation tools like IC:IDO Flexible II, IPS Cable Simulation and TEA Pipe compute the rigidity of the cable system by using substituted material properties. The high-voltage cable producers don't provide these substituted parameters. Measuring the properties during a physical experiment is inefficient because of the high time exposure and costs. The complex structure of the high-voltage cables and the high number of variants lead to the advantage of simulation opposite experiment. So the need for research is a finite element model to generate the necessary substituted material properties in a time and cost efficient way. To achieve this goal, bend and torsion tests of detailed cable models are simulated and matched with experimental results for validation. Under the premise of the plastic material behavior of the wire and the interface friction between the individual cable components, different mesh strategies are evaluated. The performance of beam against solid element meshed wires is crucial and the element size influence to the result quality is researched. For a robust convergence the complex contact problem is mapped by the Augmented-LaGrange algorithm and the fitted contact stiffness between the individual cable components. The results are the influence of the plasticity and the interface friction to the change of the stiffness properties depending on the cable load.},

abstract = {Slowly but steadily, more and more electrical vehicles push onto the consumer market. To produce electrical engines cost efficiently, in first-class quality and in sufficient quantity, it is indispensable to understand the process of winding. The prediction of the wire behaviour is one of the key challenges of coil winding. It is sophisticated and sometimes impossible to measure relevant process parameters (like the wire pull force after wire guide, the wire stress after deformation) in experiments in order to be able to investigate the process in detail. Therefore, a detailed model is built to simulate the wire behaviour during linear winding process. The finite element based simulation tool ANSYS Workbench® serves as the static structural component tool. ANSYS provides comprehensive possibilities in structural mechanics and it is possible to simulate thermal and electrical physics for future work (Co-simulation within one tool). To represent the high dynamic process of winding within this simulation, some first adaptions have to be made. This means, that dynamic influences such as rotational speed or acceleration of the coil body are neglected. Within static structural analysis, the given boundary conditions are applied to the model. The material properties of wires under scrutiny are validated by a tensile test and by the values of datasheets. In order to achieve the best convergence, different contact algorithms are selected for each individual contact behaviour. Furthermore, some adjustments to the mesh are necessary to gain significant results. State of the art in coil winding is an experimental procedure, which delivers good process parameters and, thus, expertise in winding technology. However, there are a lot of different, interacting parameters, which have to be optimized in terms of boundary conditions. The simulation model of the winding process, where varying parameters can be optimized pertaining to the optimal winding result, calls for extensive research in this field. The generated model enables users not only to influence the process parameters but also to modify the geometry of the winding body. To make the simulation scientifically sound, it is validated by experiments.},

abstract = {One of the most challenging aspects of processing electronic parts is the abundance of influencing factors. These have a significant impact on the quality of the finished product. Particularly the affinity to embed moisture in the plastic matrix can lead to severe damage mechanisms. With a moisture gain of up to 0.5 percent by weight [1] delamination and the so-called “popcorn effect” may occur during reflow soldering [2]. This is due to the explosive vaporization and volume gain the embedded water experiences during the heating process. To prevent these failures the floor time has been established. It specifies the maximum amount of time a Surface Mount Device (SMD) can be exposed to certain conditions (floor life) before failures start to occur. After the floor life ends, time-consuming and costly preconditioning in a warm and dry atmosphere is necessary to restart the floor time. The Moisture Sensitivity Level (MSL) in combination with the JEDEC standard defines the exact conditions and times for preconditioning.The proposed article focuses on modeling cause-effect-relations between influence and target values to create a more efficient way to determine when preconditioning is necessary. A literature review of research papers and industry standards is used to determine the quality defining influence parameters. Transferring these insights into two simulation models, one based on the Fickian diffusion mechanism, the other on the two-stage Fickian diffusion, leads to a promising approach for concluding reversible and irreversible moisture diffusion into the SMD components.An experimental setup is determined using the derived dependence model. The experiments consist of defined loading and drying cycles of different samples of MSL 3 and 4 to quantify the moisture de- and absorbed by the part under defined conditions. Subsequently, several differently moisture-loaded parts are reflow soldered to recreate a variety of failure mechanisms. Which, in turn, are used to verify the critical moisture mass absorbed by the SMD-components},

However, the degree of their practical implementation has to be scrutinized. To define a status quo, it is important to analyze the situation and to identify deficits, starting points and unexploited potentials.Still, a detailed understanding of the fourth industrial revolution and the digital transformation is lacking especially in small and medium sized manufacturing companies. In addition, the fourth industrial revolution is associated by most companies only with logistics as well as production and manufacturing areas. The opportunities to integrate additional functional areas of the production process and the vertical value chain into the concept of the fourth industrial revolution are hardly considered. Starting from the point of view that the fourth industrial revolution is defined as a systematic increase in the flexibility of products and processes through automation, extensive networking and decentralized control mechanisms, as well as a data acquisition and integration through information and communication technologies, a study concept is developed. For this purpose, it is not enough to ask only for the present prevalence of technologies of the fourth industrial revolution. It is necessary to analyze the processes within manufacturing companies.A survey concept is developed that initially breaks down the vertical value chain as well as the production process into specific sub-processes. These sub-processes are analyzed regarding their degree of automation and digitalization and networking among themselves. The results of this survey presents concisely the call for action, the state of implementation and realized solutions of the fourth industrial revolution in Germany. Furthermore, impulses and best practices for innovative products and business models can be given.},

abstract = {With advancing electromobility the demands regarding electrically conductive copper connections are increasing. In order to withstand the critical conditions in an electric traction motor the connections have to be stable and of high quality. Welding is a possible method to produce material bonded joints that, while fulfilling the requirements regarding electrical conductivity and mechanical stability, also allow for an increased integration density and reduced construction space by substituting screw connections. Especially laser welding offers a flexible, fully automatable approach while only needing single-sided optical access to the welding spot. While being an established industrial process, the joining of copper via laser-welding is still classified as difficult. The high thermal conductivity and low absorptivity of copper for infrared wavelength is challenging for a stable welding processes and sensitive to different material properties like material thickness, oxidation and roughness. Green wavelengths have significantly higher absorption rates at room temperature and are less sensitive to absorption-dependent material properties. The advantages are clearly visible in heat conduction welding applications. If these advantages are also applicable to a deep penetration welding process is investigated in this paper. The results are compared with weld seams produced by state-of-the-art industrial infrared lasers.},

Simultaneously electrical energy storage is gaining importance within rural distribution networks to compensate fluctuating generation plants. A hybrid compensation system includes a transformer, a multi-phase inverter, diverse storage systems and a communication-capable control unit, which may be connected to the control center of the distribution system operator (DSO).

abstract = {The current trend in internal value stream structures shows a clear
development towards a combination of the specific advantages of the
operation-oriented and the process-oriented production systems. All
scientific approaches have in common that flexible intralogistics
production networks require an autonomous and intelligent transportation
systems that is not designed for a specific task, but can take on
different transport roles due to their versatility. However, a
comprehensive analysis of current designs and research projects in the
field of AGVs and intralogistics transport robots show that there is
neither the necessary interoperability of different systems nor a system
architecture that addresses a flexible material flow independent of the
physical design of the transportation system. AGVs mainly have a
central control system, which manages the generation of transport orders
and their disposition on the vehicles. In addition, the routes are
specified centrally for the vehicles, even if they have free navigation.
The individual transport unit is therefore only an executing machine
that processes the assigned transport orders without any influence on
order dispatching or route planning. Therefore, these AGV approaches do
not have the flexibility and autonomy required for an intralogistics
production network. The research project addresses the necessary
interoperability of logistics systems and the abandonment of proprietary
standalone solutions. For this purpose, methods for digitizing the
workspace, route planning and path execution using a service-oriented
architecture (SOA) were developed. A central component of this
architecture is the approach described in the paper to enable
decentralized path planning on the vehicles. Therefore, the path
planning must be applicable to different target platforms without
implementation effort and the vehicle software must be designed
independently of the application. This approach allows intralogistics
systems to be flexible and adaptable, resulting in a more sustained use
of these system},

The increasing integration of power electronics in various applications like energy
distribution, hybrid and electric mobility or consumer products requires a steady improvement of
interconnection technologies in order to increase reliability, efficiency and life expectancy of power
modules.
Currently the standard technology used for top level interconnection is the aluminum wire bonding
process. Thereby wires are friction welded both on dies and substrates by the use of ultrasonic in
order to create a local cohesively connection. Due to the limitation of aluminum regarding the
mechanical, thermal, and electric characteristics, the use of alternative materials like copper is
preferred. However, due to the higher hardness of copper, copper wire bonding on the previous
aluminum metallization of the components is not possible, so that an additional copper metallization
is necessary to be applied. Common processes for the metallization of semiconductors like PVD or
galvanic metallization are either expensive or require extensive follow up processes like back etching.
In order to provide another suitable method a plasma based coating unit for copper particles has been
installed.

abstract = {Achieving the urgent need for rapid decarbonization to meet the 1.5 °C target requires disruptive technological change. In the automotive industry, technological progress is closely linked to improved sustainability, and sustainability goals drive the need for technological innovation. However, new technologies in the mobility sector are fraught with uncertainties that challenge both original equipment manufacturers (OEMs) and their stakeholders, such as suppliers, customers, and policy-makers. Therefore, this chapter focuses on the technical, economic, and environmental evaluation of alternative powertrain concepts and the management of uncertainties associated with emerging technological innovation as part of the broader transition to net zero.
Electric mobility plays a central role in the sustainability transition and is characterized by a high degree of variance. Battery electric vehicles (BEVs) are expected to dominate private transport in the future due to their greenhouse gas and pollutant-free operation and high efficiency. In addition to charging infrastructure, the technical challenges currently lie primarily in cell chemistry and power electronics. Advances in battery technology and infrastructure electrification will help eliminate the range problem in the future. Another important future fuel is hydrogen. One application is the fuel cell vehicle, which combines the advantages of a chemical energy carrier with high gravimetric energy density with those of an electrical energy converter. Hydrogen also plays an important role as an energy carrier for specific energy supply processes in manufacturing processes and simplifies the transport of regeneratively generated energy. In addition, hybrid vehicles are a transitional technology, and alternative fuel internal combustion engines can contribute to the decarbonization of the existing fleet and to specific applications.
This chapter assesses the performance of alternative powertrains; highlights the interrelationship between powertrain systems, energy ecosystems, and sustainability goals; and identifies future research directions for electric and hydrogen mobilit},

In the second method, also other energy resources rather the electrical energy consumption is considered. This method assesses the quality of resource conversion in the soldering process in the product level. In this paper, firstly, the system of the least energy demand as crossbench reference value is explained. The basic idea of this calculation is the comparison and evaluation of electrical energy efficiency based on the ratio of the theoretically required energy consumption to the measured electrical energy consumption. In the second method, the model quantifies the resource consumption and qualifies this consumption using the exergy analysis method. Exergy efficiency is the fraction of the work potential of the heat that is converted to work, and it illustrates the quality of consumed resources during the soldering process. Transparency and comparison of these two methods derives the measures to analyze and improve the major energy saving potentials in the soldering oven technology.},

abstract = {The direct additive manufacturing, such as Direct Ink Writing (DIW), of silicone parts holds cost and complexity advantages. However, for extruding strands of low viscosity heat curing silicone rubbers, a build plate temperature of up to 90°C is used, which comes with the challenge of early vulcanization inside the printhead. Thus, this paper presents a thermoelectric cooler for universal printheads. At a build plate temperature of 90°C it prolongates vulcanization by 198.5 % (∆tpot life = 508.8 s), which allows a reduction of print speed for higher quality. Additionally, the influence of external temperature is reduced and the viscosity can be controlled.
To reflect the growing importance of interoperability (i.e. the ability of systems to purposefully interchange interpretable information) as a requirement for the product within the design phase of technical systems, this paper introduces “Design for Interoperability” (DfIOp) as a new DfX principle. First, this is motivated by the ever-growing importance of information technology for current and future products. Then, the main contribution of the paper is the combination of the state of the art in the research domains of DfX, interoperability, Systems Engineering and Industry 4.0. Consequently, DfIOp will be presented, including a systematization model as well as a first method for its implementation. Further contemplation on DfIOp shows, that it enables derivative principles such as “Design for Data Analytics” and “Design for Digital Twin”. In future research, the underlying models as well as methods of DfIOp are to be further detailed and integrated into the research context. els have been able to successfully establish themselves and become part of our everyday lives (e.g., Uber, Amazon). In the context of the digitalization of products, production systems and processes, the importance of digital platforms is also increasing in the industrial business-to- business (B2B) market. Network effects, which arise when the number of users has an influence on the value of other actors, are named as a decisive mechanism for the success of platform business models. Previous studies focused on successful platform examples from the B2C mar- ket. A detailed investigation and differentiation of the effects occurring in the manufacturing industry is currently missing. In order to better illustrate the effects for industrial applications, nine practical examples were prepared in this paper using a value-oriented methodology. Based on this, they are analyzed for the influence of an increasing number of participants of the roles involved. Thereby, six different network effect types could be identified, which differ in their characteristics between certain roles and can be traced back to different value propositions. This typification should lead to a more detailed understanding of network effects in industrial value networks and thus support companies in using these effects in a focused approach building their platform business model.

In einigen dieser Anwendungsfelder wie bspw. bei der Fabriklayoutdigitalisierung oder dem innerbetrieblichen Materialtransport konnte die Verwendung von UAS bereits erfolgreich getestet und validiert werden. Der aktuelle technische Entwicklungsstand von UAS für Flugregelung, Kollisionsvermeidung und Flugleistung lässt grundsätzlich den Einsatz im Produktionsbetrieb zu. Ungeklärt ist weiterhin, welche rechtlichen und somit auch versicherungstechnischen, technischen und betrieblichen Voraussetzungen von anwendenden Unternehmen für die Verwendung im Produktionsbetrieb geschaffen werden müssen.
In diesem Whitepaper werden rechtliche und versicherungstechnische Fragen diskutiert. Anschließend wird eine technische und betriebliche Risikoanalyse vorgestellt, die um einen Maßnahmenkatalog für eine fachgemäße Einführung und Anwendung der UAS-Technologie ergänzt wird. Dabei werden mögliche Risiken betrachtet, auch wenn mit zunehmendem Automatisierungsgrad von UAS die Risiken durch Sicherheitsmechanismen und entsprechende Sensorik verringert werden können.

The market for robot‐centric automation (RA) solutions is a global growth industry. Nevertheless, due to the high cost and complexity of robotcentric automation solutions, small and medium‐sized enterprises (SMEs) often fall short of this trend.
Subject and objective of the dissertation is the creation of efficient and scalable engineering concepts and solutions for the planning of RA solutions based on web technologies. For this purpose, the engineering configurator concept, a microservice‐based web platform reference architecture, and a development method required for engineering configurators based on
three sub‐methods (W1‐W3) were introduced. Via user‐centered development approaches, a modular architecture for RA solutions as well as approaches from knowledge‐based configuration (subfield from artificial intelligence (AI)), sales, planning and engineering of robot‐centered automation solutions are made accessible to a broader audience. The
concepts and methods were validated in the context of the ROBOTOP web platform as well as by means of various 3D web, AR (Augmented Reality) and VR (Virtual Reality) multi‐user demonstrators. The concepts and methods thus also enable efficient digitalization or process automation of the engineering of RA solutions through the introduced, structuring methods for knowledge acquisition, modeling as well as implementation and thereby support the vision of the digital twin in the context of Industry 4.0.
