Abstract


Laser cutting currently represents the most common

laser-based process in production technology. With the

ongoing development of remote laser cutting

technologies, such as remote fusion cutting and remote

ablation cutting, its field of application will widen even

more.

Exploring these processes, simulations offer major

advantages compared to experiments. Not only do they

offer insight into process variables that are not or only

hardly accessible experimentally, but they also allow

us to investigate cutting with process parameters that

are not even experimentally available yet, e.g.

alternative beam sources.

Therefore, we refined our transient, numerical

simulation model for laser-material processing and

applied it on laser cutting. In contrast to other

simulation models which focus on certain aspects, our

model has a comprehensive objective, which enables

us to examine various laser-material processing

techniques with the same universal model.

After introducing the model, we present results on the

process dynamics of Remote Fusion Cutting and

Remote Ablation Cutting. For comparison, we show

current results on gas-assisted fusion cutting and

demonstrate that our results agree well with

experiments. Conclusively, we present how laser

characteristics, such as polarization and beam profile,

influence the process dynamics, which will become

increasingly important with the development of new

beam sources.
