Problems solved by technology

[0003] The current laser microtexture processing methods mostly rely on the control scheme of the existing CNC machine tool system. However, the control method of the traditional CNC machine tool system is often closed within the system framework. The control method is cumbersome and bloated, and the openness is low. For example, on a multi-axis machine tool equipped with high-performance lasers, laser micro-texture processing of workpieces with various shapes requires the design of special processing methods for laser micro-texture processing requirements.

[0004] At present, the laser microtexture processing method still has the following shortcomings or deficiencies: (1) The movement accuracy of the machine tool is low, which cannot meet the high precision requirements of laser microtexture processing; (2) The openness of the control method based on the existing CNC machine tool system Low cost, cumbersome operation, machine tool motion G code needs to be manually written by the operator, and the efficiency is low; (3) The selection of processing technology is scarce, and the visibility of the processing effect is poor, which cannot meet the processing requirements of various workpiece shapes and textures, and cannot be processed in real time. Monitor processing progress

(4) The synergy between laser and machine tool linkage control is low, the positioning accuracy is low, and the processing quality is difficult to guarantee
