Manufacturing structural component with high surface quality by shaping involves introducing through hole near anticipated excess of material, whereby removed material corresponds approximately to previously determined excess

摘要

The method involves shaping a flat or already pre-shaped component (1) with at least one through hole (9) in the deformation region to achieve fold or crack-free material deformations. It involves detecting an excess of material arising in the deformation region by buckling (7), introducing the through hole near the anticipated excess of material, whereby the removed material corresponds approximately to the previously determined excess, and shaping the component.
