AI Technical Summary

Problems solved by technology

Ultrafast pulsed lasers have also been gradually applied to laser etching processes. Although the processing accuracy is high, the processing efficiency is low and it is difficult to meet the needs of mass production. Compared with ultrafast pulsed lasers, ordinary pulsed lasers have lower processing efficiency. High but low machining accuracy

It can be seen that it is difficult to achieve a good balance between the processing accuracy and efficiency of the current laser etching technology.

In addition, most of the existing domestic laser etching equipment can only process two-dimensional planes, and there is a lack of laser etching equipment for three-dimensional complex curved surfaces, and few such equipment rely on complex path programming and planning for processing. Greatly affects the laser etching efficiency of three-dimensional complex surfaces
