Abstract

A shaped part is made by forming in a flat steel plate a thickness-reducing groove and hot-shaping and hardening the flat steel plate into a three-dimensional shape. Then the plate formed with the groove is cooled, and a piece is sheared off the cooled plate along a cut line in the groove.
