Abstract

Rollover for a part generated by virtual fine blanking is predicted and determined prior to producing the part. A digital image, in particular the cutting contour of the part, is generated, provided as an image file and subjected to image analysis in an image processing device. The image analysis provides individual color gradations of the cutting contour. The gradations are associated with a residual thickness in the region of the cutting contour, so as to be indicative of rollover.
