The paper provides an overview over the main building stones of modeling of laser manufacturing common to all processes and describes the most important processes. As an example for modeling of a well established process cutting is then treated in detail. Moreover a new process is described and analyzed, where forming by mechanical forces as conventional deep drawing is augmented by selective laser heating in those regions of the workpiece, where locally strong deformations take place and thus a reduction of the yield strength is beneficial. Experiments have shown, that the forming forces can be reduced by up to 30% and that with materials that cannot be formed in a cold state without cracks or rupture very good forming results are obtained. A theoretical analysis of the latter process agrees well with the experiments and allows predictions for practical applications.
