| 摘要 |
The invention relates to a method for the precision machining of a workpiece (3) arranged in the working zone (1) of a machining laser (2), a laser measuring beam (10) being blended into the beam path of the laser machining beam (5), and the laser beams being deflectable in two orthogonal directions by means of controlled galvanometer mirrors (7). The invention consists in the fact that the workpiece surface, the shape and size of which are known, is scanned by means of the laser measuring beam (10), and the light of the laser measuring beam (10) reflected from the workpiece surface is utilised for detecting the position of the workpiece (3) inside the working zone (1) of the machining laser (2). <IMAGE> |
