Abstract

A method of making a motor vehicle component by hot-forming, hot-cutting, and press-hardening a plate made of a hardenable steel sheet alloy, heating to a temperature greater than Ac1, inserting in a combined forming and cutting tool, fixing the inserted plate in the forming and cutting tool using a stamp which is arranged in the inner region of the tool, at least partially circumferential edge cutting before beginning the forming operation or during a time period of up to 50% of the forming progression and/or at least 20% of the press stroke prior to the bottom dead center position, and hot-forming in a press stroke with the edge cut and optional press-hardening.
