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.

A method for generating openings in a metal foil, the method comprising 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 vicinity of the bends by a cutting production process forming chips including an abrasive removal by a grinding disk having an undefined cutting edge simultaneously cutting a plurality of adjacent extrema of the metal foil.
