Shear cutting of press hardened steel: influence of punch chamfer on process forces, tool stresses and sheared edge qualities 
Abstract:
In order to cope with the difficulties of shearing operations of press hardened steels, this work attempted to optimize these processes. Herefore, it is necessary to reduce the press forces and stresses in tools, while still obtaining adequate sheared edge quality levels. To reach this goal, different punch chamfer angles (0°, 2°, 7° and 20°) and relative cutting clearances (5, 10 and 15 % of the sheet thickness) were tested in a cutting tool, which was adapted in a way that different active ele...    »
