Research
Interests
Dr. Weinmann’s
research focuses on manufacturing processes with emphasis on metal forming and
tribology in metal working. Currently he is designing/constructing a next-generation, sheet-metal drawing die
Incorporating active drawbeads to control the material flow in the die. He is involved in developing sensors
capable of recording tangential and normal forces in sheet metal forming at the tool-sheet interfaces. His
interests also extend to superplastic forming of automotive sheet, and the mechanics of chip formation and
tool life in machining.
