The representation of production processes in digital simulation models is an utterly important, but also challenging task. The simulation models allow a deepened understanding of processes and enable an optimization of them. In order to simulate subtractive and additive production processes, the so-called Particle Finite Element Method (PFEM) is used. The PFEM unites the advantages of particle based methods for the characterization of complex topological changes with the possibility of accurate material modeling via the FEM. The central method for the connection of the particle based approach with the FEM is the α-shape-method, which was adopted from computer graphics.
