Performance and Accuracy of the Shifted Laser Surface Texturing Method

Original language description

Shifted laser surface texturing method (sLST) was developed for increasing of production speed of functional surface textures to enable their industrial applicability. In this work, the shifted method is compared with classic methods on real texturing example with focus on achieving highest processing speed. The texture accuracy is assessed by size and circularity measurement with use of LabIR paint and by depth profile measurement using contact surface profiler. Heat accumulation temperature difference was also calculated. The classic methods (path filling and hatch) performed well (deviation ≤ 5%) up to certain scanning speed (0.15 and 0.7 m/s). For the shifted method, no scanning speed limit was found up to the maximum of the system (8 m/s). The depth profile shapes showed similar deviations (6 to 10%) for all methods. The shifted method in burst variant achieved highest processing speed (11 times faster, 146 mm2/min). The shifted path method achieved highest processing efficiency per needed laser power (64 mm2/(min·W)). The heataccumulation was minimal for the shifted path method (3 K). Laser usage efficiency of different methods was compared. The shifted path method (99% efficiency) is very promising. Its advantages in combination with GHz burst machining and multibeam were highlighted.
