Abstract
Within the manufacturing process of sheet metals, blanking represents an essential process operation. As the industrial application of high-strength multi-phase steels grows, the blanking process must consider high blanking and shear forces, which are characteristic for processing these materials. This paper presents options for reducing these forces. Experiments were performed utilizing a novel tool concept, which can correlate necessary blanking forces to the punch stroke in three dimensions and in the direct force path. Results from three different AHSS materials are presented showing the variation of decisive blanking parameters such as die clearance, shearing angle and sheet positioning angle.
