The Finite Element Analysis (FEA) is a suitable
tool for the process design and the determination of
technical failure. Within this paper, the FEA is used for
simulating and analyzing the thread milling process and the
tapping process for reinforced lightweight extrusion profiles.
Two different finite element models are developed to
simulate both processes. An elastic material behavior is
implemented in the simulation. For the tapping process, the
computed stresses during the process as well as the geometrical
displacements are considerably higher than the
stresses computed for the thread milling operation. This is
caused by the lower mechanical loads occurring in the
thread milling process. The results can be used to identify
areas of high stresses which may cause material failure.
Moreover, both processes can be analyzed with respect to
their influence on the workpiece. The simulation results are
compared to experiments.
