Problems solved by technology

If you want to process complex graphics, using the ordinary graphics trajectory processing method will cause the influence of acceleration and deceleration during the continuous laser switching process, resulting in inconsistent processing speed, which will make the laser processing quality worse, and black spots or light spots will appear.

Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description. It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0045] The invention provides a laser processing control method, the method comprising:

[0046] Set the extension trajectory respectively for the processing trajectory forming a corner in the pattern to be processed;

[0047] Control the laser to move along the extended trajectory, so that the laser starts to move along the processing trajectory according to the set processing speed.

[0048] In the laser processing control method provided by the present invention, the extension trajectories are respectively set for the processing trajectories forming corners in the pattern to be proces...

Abstract

The invention relates to the field of laser processing, and concretely relates to a laser processing control method and device, and a computer storage medium. The method comprises the following steps:setting extension tracks for processing tracks forming corners in a to-be-processed pattern; and controlling a laser to move along the extension tracks to make the laser start to move along a processing track according to a preset processing speed. Extension type motion processing is carried out on the inflection point of the processing track, so that the problem of poor processing quality causedby sudden change of the motion speed of laser light at the inflection point of the graph in the laser processing process is solved.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a laser processing control method, device and computer storage medium. Background technique [0002] At present, the cutting and etching of most materials rely on machining or EDM. For the processing of some sensitive materials (glass, ceramics, etc.) and high-precision processing requirements, mechanical and EDM cannot meet their needs. Laser processing has the advantages of high precision, high efficiency, no thermal influence and material restrictions, and is the best choice for high-precision processing and sensitive material processing in the future. [0003] Based on its own principle and characteristics, laser processing has extremely high requirements on the quality of laser processing. At this stage, laser processing is often closely related to hardware such as motion control and galvanometer. The processing task is completed by controlling the motion axis, laser and gal...
