Explicit finite element analysis for rotary cutting of electrical steel sheet

Rotary cutting of rotor and stator laminations complements the available methods in the processing of electrical steel sheet. Furthermore, with this process, a technological answer to the production of ever-thinner laminations can be found in which high-speed stamping is reaching its technical limits. This paper explicates a finite element analysis for the rotary cutting process of electrical steel. First an overview of the cutting process and its peculiarities is given. Then the setup for the FEM simulation and its material model are explained. Finally followed by a discussion of simulation results with different parameters.
