Laser micro structure machining method

Abstract

The invention discloses a laser micro structure machining method. The laser micro structure machining method includes the following steps that a three-dimensional movement model of a machine tool is built, the real-time positions of a linear shaft and a rotating shaft of the machine tool are converted into machining machine tool coordinates; a to-be-machined workpiece is moved to a machining position, the machining position is set to be a machining original point, and a machine tool coordinate system is updated; machining position parameters are read, and laser machining position coordinates are calculated and obtained; according to the coordinates, a machining schematic diaphragm is calculated and generated, and analog simulation is performed on the machining effect; G codes are generatedaccording to the coordinates, and used for path planning of a movement platform in machining; and a controller controls a machining machine tool to move according to the G codes, the obtained laser machining coordinates and machining machine tool coordinates read in real time in the machining process are compared, when the obtained laser machining coordinates and the machining machine tool coordinates read in real time in the machining process are consistent, it is considered that the workpiece moves to an assigned position, and therefore a laser device is controlled to emit out light, and laser micro structure machining is performed. The laser micro structure machining method can achieve high precision machining, improves the control synchronism of the laser device and machine tool movement, and effectively improves the laser micro structure morphology observing difficulty.

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 micro-texture 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 micro-texture 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 real-time Monitor processing progress

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