Laser radiation process for removing or melting material layers from workpiece using radiation energy, involves using scan system or scan head, which can be laterally shifted, to lead laser radiation towards removable layer of workpiece

摘要

The method involves dividing the removable or meltable layer (1) of a workpiece into quadrants (2-5) which are adjoined by area boundaries (6,7). A scan system or scan head, which can be laterally shifted, emits and leads laser radiation towards the quadrants of the removable or meltable layer to clear away the removable or meltable layer in predetermined depth.
