A large format laser processing method

Abstract

The invention discloses a large-format laser processing method. The large-format laser processing method is suitable for processing a laser processing machine tool with galvanometer processing as a main processing mode, the laser processing machine tool comprises a laser, a galvanometer, a light path system, a machine tool three-axis motion platform, a motion control card, a galvanometer control card and a computer. According to the large-format laser processing method, the processing graph exceeding the processing amplitude of the galvanometer is automatically divided into a plurality of small areas smaller than the processing amplitude surface of the galvanometer, the processing positioning point of each area is obtained, and then optimizing the processing track of each area and a positioning movement track among the small areas, positioning is carried out according to the optimized processing sequence of each small area, and the pattern of each small area is processed through the galvanometer until all the small areas are processed. According to the large-format laser processing method, automatic segmentation, trajectory optimization and processing process control of a large-format graph are realized, the processing process of the large-format graph is simplified, and the processing quality and the processing efficiency are improved.

Description

technical field [0001] The invention belongs to the field of laser processing equipment, in particular to a large-format laser processing method. Background technique [0002] The laser processing machine tool includes a machine tool axis motion system and a galvanometer scanning system. It adopts a splicing processing method to position the workpiece through the axis movement, and the laser scanning galvanometer performs laser processing. The galvanometer processing has fast response, high processing accuracy and high speed, and is widely used in laser processing. However, the scanning range of the galvanometer is limited, and the larger the scanning range, the worse the accuracy, so the scanning range of the galvanometer will be limited in actual processing. For large-scale processing patterns that exceed the maximum scanning range of the galvanometer, it needs to be divided into several small patterns, and each small pattern is positioned by the movement of the machine t...

Problems solved by technology

Although the auxiliary movement does not directly participate in the cutting of the workpiece, it is an indispensable part of the processing and will consume a certain amount of processing time

At the same time, the sequence of the drawn graphics is the actual processing sequence. Generally, the drawn processing graphics are in a disordered state, especially after the segmentation, the processing sequence of the graphics is more chaotic, which affects the processing efficiency. There is no continuous processing in the process, which will adversely affect the processing quality
