Scientific Abstract

The comprehension of geometric part deviations and their manufacturing and assembly related sources as well as the investigation of their effects on the function and quality of technical products builds the framework for the planned research group “process-oriented tolerance management based on virtual computer-aided engineering tools”. The aim of this research group is the provision of holistic methods and efficient tools for the comprehensive management of geometric deviations along the product origination process, which are to be validated in a model factory. In doing so, a particular focus is set on the development of a procedure for the fruitful cooperation of all departments involved in geometric variations management, from product development, to manufacturing, to assembly and to metrology, which will enable companies to quickly specify functional tolerances, which are manufacturable and measurable, and consequently to save costs and to reduce the time to market.

In this regard, the vision of the research group is to enable the close collaboration of product development, manufacturing, assembly and metrology in computer-aided tolerancing, i. e. the joint formulation of functional tolerances, which are manufacturable and measurable. By enabling this close collaboration, all manufacturing and assembly related sources of later problems regarding the product function and quality can be considered already during early phases of virtual product and process development. As a consequence, tolerances can be specified efficiently and optimized inspection plans as well as robust manufacturing and operating windows can be identified, which allows the development of robust products to be manufactured and measured at low costs.   

Since geometric part deviations are inevitable and affect the function and quality of technical products, their management along the product origination process is essential for the development of functioning products, which conform to the quality and usage requirements of customers and are successful on international markets. As a consequence, tolerance management is a fundamental task in product development and reaches various fields of industry, from consumer to industrial goods. Due to steadily increasing requirements on quality and efficiency, it strongly gains importance not only with large, but also small and medium-sized enterprises. In this context, the industrial application of the scientific findings of the research group will contribute to the success of the German economy.
