T07 - Tool Topography

Functionalisation of tool topographies for material flow control and tool life optimisation

Project Status: Active

Last Update: 10.07.2019


The transfer project T07 focusses on the material flow control using functional surface structures on forming tools. The main objective is to develop methods for process optimisation of the combined sheet-bulk metal hot forming (SBMHF) based on the knowledge of sheet-bulk metal forming operations. The processes developed for micro- and high-feed milling for the manufacturing of surface structures are adapted to the hot work steel required for hot forming. In addition to the new development of suitable cutting edge modifications for micromilling tools, the tribological relationships between friction, temperature and topography of the functional surface structures are to be determined in an adapted ring compression test. Finally, the findings will be verified in industry-related tests.
