Abstract
A process for the defined adjustment of the shapability of a metal semi-finished product is known, in particular in the shape of sheet or strip material, by means of laser radiation, for a subsequent shaping process, by which laser radiation is applied to the workpiece surface, whereby the coordinates of the workpiece and the laser radiation are moved temporarily in relation to each other. In order to further develop such a process, the laser radiation is continuously applied to the workpiece in such a way that a track is produced on the workpiece, said track lying in the region of the target-bending, target-punching-bending or even deep-drawing deformation to be performed, said deformation representing a recrystallization zone.
