Abstract
In a process for producing precise cut surfaces on a workpiece by stamping or blanking, in particular by fine-edge blanking, a contour first is stamped or blanked out at a distance (a) from the actual contour of the workpiece, and the workpiece then is scraped down to its final contour. It is intended here, in a first step, for only up to part of the thickness (d) of the workpiece to be scraped and, in a following step, for the contour of the workpiece to be achieved by scraping in the opposite direction to the first step.
