Constitutive friction law for the description and optimization of tailored surfaces
(Third Party Funds Group – Sub project)A central challenge insheet-bulk metal forming is a partially uncontrolled material flow. Thisworsens the achievable geometrical accuracy of the parts. In this context, theobjective of the project is to control the material flow by local adjustmentsof the friction by modifying the workpiece or tool surface. Hereby, the diefilling of the functional elements is improved. Especially tool-sidedmodifications have a high potential, since they do not extend the processchain. However, for an efficient application, they must offer a high wearresistance, which is why the functional relationships between wear-inducedchanges in the tool topography and friction are being researched.
