Research on Structure and Control System of Laser Surface Texturing Machine

摘要

Existing laser honing machines all utilize the motion mode of workpiece movement. But as to complex workpiece, this mode is inappropriate to use. For example, cylinder liner, precasted into the engine block, is not suitable to rotate when fixed on the chuck, because the block is irregular and heavy. This equipment uses the mode of laser head rotation and linear motion. The workpiece keeps still during the laser texturing process. In this paper, the structure design and control principle of the laser machine are narrated in detail. The process of the machine is a new method of laser micro-texturing, named as "single-pulse interval of the same point many times". The method contributes to processing microscopic or macroscopic morphology and significantly reduces the negative thermal effects of laser processing.
