Abstract

The present invention relates to a method for producing a dimensionally stable sheet metal component, wherein the method includes preforming a metal sheet into a sheet metal preform comprising at least one base region, a frame region, a transitional region between the base region and the frame region, optionally a flange region and a transitional region between the frame region and the flange region, wherein at least one of the regions comprises excess material at least in portions. The sheet metal preform is cut at least in portions to form a cut sheet metal preform with a sheet metal preform The sheet metal preform is one of swagged and calibrated which has been cut at least in portions to form a substantially finished formed sheet metal component.
