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.
