| 20210402520 | METHOD FOR THE MATERIAL-REMOVING LASER MACHINING OF A WORKPIECE - A method for the material-removing machining of a workpiece by laser beam pulses. The laser beam pulses are directed to impact points on the surface of a volume to be removed of the workpiece in order to cut away material from the volume to be removed. Cutting away the volume to be removed results in a new contour surface to be produced on the workpiece. An impact angle of the laser beam pulses relative to the contour surface to be produced is set in accordance with a predefined condition during the removal of at least part of the volume to be removed that directly adjoins the contour surface to be produced. According to this condition, the impact angle is the same as a threshold angle (as), or somewhat smaller. The threshold angle corresponds to the impact angle at which an effective laser energy density at the impact point of the laser beam pulses on the contour surface to be produced is equal to a threshold fluence. Material is only removed at an impact point if the effective laser energy density is greater than the threshold fluence. As a result, only those volume elements of the volume to be removed that are adjacent to the desired contour surface to be produced are cut away. By controlling, in an open- or closed-loop manner, the impact angle it is therefore possible to generate with very high precision the desired contour surface on the workpiece. | 2021-12-30 |
