Problems solved by technology

[0003] Therefore, when the traditional laser processing system processes the material surface, the spot parameters are set before processing, and the scanning path in the processing pattern is sent to the galvanometer system through a control system, and the galvanometer system scans until the processing pattern is drawn. The parameters cannot be dynamically adjusted during the movement, and the effect style processed by this method is relatively simple

Abstract

The invention provides a laser surface machining method and system. The method comprises the following steps of machining drawing file decomposition, specifically, obtaining a machining drawing file,decomposing a machining path of the machining drawing file into a plurality of sub-paths according to a gray scale value, obtaining a boundary coordinate of gray filling of each sub-path, and settinga galvanometer scanning coordinate according to the boundary coordinate; obtaining machining data, which is used for a gray scale laser parameter index table in the machining drawing file, wherein thegray scale laser parameter index table at least comprises a gray scale value of the machining drawing file and a laser parameter corresponding to the gray scale value; and scanning machining, specifically, dynamically adjusting the laser parameters corresponding to each sub-path according to the gray laser parameter index table, and sequentially scanning each sub-path until the drawing file machining is completed. According to the laser surface machining method and system adopting the scheme, the laser parameters are dynamically adjusted in the laser machining process, so that the machining effect has diversity and flexibility.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a dynamically regulated laser surface processing method and system. Background technique [0002] Traditional laser surface processing systems generally use vibrating mirrors to control the moving direction of the spot. In most cases, the same spot parameters are used for the moving path of a single spot, and even the same parameter is used for the entire processing process when processing some special patterns. [0003] Therefore, when the traditional laser processing system processes the material surface, the spot parameters are set before processing, and the scanning path in the processing pattern is sent to the galvanometer system through a control system, and the galvanometer system scans until the processing pattern is drawn. The parameters cannot be dynamically adjusted during the movement, and the effect style processed by this method is relatively si...
