Research Projects

On the forming side, stamping technology is a pillar of competence that has been significantly shaped in the history of the chair by Prof. Hartmut Hoffmann and Dr. Roland Golle.

With modern stamping presses and many creative experimental setups, the focus is on creating a deeper understanding of press, die and cutting result as well as die wear.

Current research projects deal with:

• prediction and quantification of the risk of edge cracking during the forming of shear cut plates,
• strategies and measures for increasing the tool life of cutting tools,
• increasing the efficiency of electrical machines by optimizing the processing of electrical sheets,
• improvement of the fatigue strength of shear-cut edges,
• accurate measurement of process-relevant variables (degree of deformation, temperature, etc.) in the cutting zone
