Method of Surface Layer Removal from the Surface of Geometrically Complex Edges of Cutting Tools using Laser Stripping Method

Popis výsledku v původním jazyce

Following clamping of the tool to the ultra-short pulse laser system, the tool rotation axis, lead angle of the tool helix, tool diameter reduction in the cutting portion, and tool edge (11) geometry are detected and analyzed using the camera system with illumination feature. Based on these analyses and knowledge of the depth of field of the laser beam, the splitting up of the portion of the tool surface being processed to the segments (10) is carried out. The laser stripping follows by scanning of the laser beam of the ultra-short pulse laser system within the defined orientation relative to the tool axis; the surface layer (2) in said segment (10) of the surface of statically fixed tool is removed. The laser stripping ends after the surface layer (2) of said surface segment (10) of the tool is removed. For the next surface segment (10), the tool position changes by the increment, and the laser stripping according to previous step is carried out for the next segment (10). Determination of the ablation attributes of the surface layer (2) prior to removal of the surface layer (2) to determine the laser parameters is favourable. ### The patent is exploited by its owner.
