The cutting process is characterised by large deformations and large configurational changes. Especially the formation of chips and burrs pushes established modeling techniques to their limits. To overcome these difficulties, the particle finite element method (PFEM) combines the benefits of discrete modeling techniques and methods based on continuum mechanics. In this work an outline of the PFEM algorithm is provided and the method is tested in a comparison to the standard finite element method (FEM). The influence of the boundary detection within the PFEM algorithm on the structural integrity of the material is studied and the numerical examples include a tensile test as well as cutting simulations, and parameter studies on important process parameters in cutting.
