A central challenge in sheet-bulk metal forming is a partially uncontrolled material flow. This worsens the achievable geometrical accuracy of the parts. In this context, the objective of the project is to control the material flow by local adjustments of the friction by modifying the workpiece or tool surface. Hereby, the die filling of the functional elements is improved. Especially tool-sided modifications have a high potential, since they do not extend the process chain. However, for an efficient application, they must offer a high wear resistance, which is why the functional relationships between wear-induced changes in the tool topography and friction are being researched.
