Abstract:
A method for generating openings in a metal foil includes at least the following steps: a) providing a planar metal foil, b) generating bends defining extrema in the metal foil, and c) generating at least one opening in the vicinity of the bends through the use of a cutting production process forming chips including simultaneously cutting a plurality of adjacent extrema of the metal foil by using grinding tools.
