Abstract

A multiplicity of laser diodes aim laser light directly onto the surface of a workpiece and are disposed over and according to the to-be-shaped contour of a workpiece, so that a detector unit for determining the spatial shaping of the workpiece and an evaluation and control unit can determine process parameters for further illumination in dependence on a comparison of an actual state of shaping and a desired state of shaping of the workpiece.
