Title:
METHOD AND CONTROL DEVICE FOR MACHINING A WORKPIECE SURFACE BY MEANS OF A LASER
Document Type and Number:
WIPO Patent Application WO/2018/146018
Kind Code:
A3
Abstract:
The present invention relates to a method for machining at least one workpiece surface in order to apply a texture pattern to at least one portion of the workpiece surface by means of a laser, especially in a numerically controlled machine tool, on the basis of image data which indicate an image of the texture pattern to be applied to the at least one portion of the workpiece surface, and model data which indicate a three-dimensional geometry of a surface shape in accordance with the at least one portion of the workpiece surface. To this end, control data are generated on the basis of track segment data, which in turn are generated on the basis of the image and model data. For every track line the control data specify one or more segment sequences and every segment sequence has track segments along which the laser is guided in order to apply the texture pattern to the at least one portion of the workpiece surface, wherein the track segments of a segment sequence comprise one or more laser track segments which the laser overtravels at a substantially constant desired machining speed when the laser is switched on.
