Blanking is one of the most important processes for manufacturing sheet metal parts with complex geometry in high precision. Abrasive wear of the cutting edge and adhesive wear of the lateral surface of the punch as a result of the high sliding speed and local pressure have a decisive influence on the tool life. In addition to the forces in the cutting phase, the clamping force by the punched sheet during punch withdraw has a significant influence on the wear on the lateral surface. The FE simulation used in this work enables an estimation of the tribological stress collective in all relevant process phases. The model is validated using experimental investigations on a test tool with different punch wear conditions and cutting parameters. Detailed parameter variations are then carried out to investigate the influences of different process parameters on the load of the tool and the resulting geometry.
