In laser marking, the extremely thin laser beam after focusing is like a cutter, which can remove the material on the surface of the object point by point. Its progressiveness lies in that the marking process is non-contact processing, which does not produce mechanical extrusion or mechanical stress, so it will not damage the processed object; Because the size after laser focusing is very small, the heat affected area is small, and the processing is fine, some processes that cannot be realized by conventional methods can be completed.
The "tool" used for laser marking is the light spot after focusing. No additional equipment and materials are required. As long as the laser can work normally, it can be processed continuously for a long time. Laser processing is fast and cheap. Laser processing is automatically controlled by computer, and no human intervention is required during production.
What kind of information can be marked by the laser is only related to the content designed in the computer. As long as the manuscript marking system designed in the computer can recognize it, the marking machine can accurately restore the design information to the appropriate carrier. Therefore, the function of the software actually determines the function of the system to a large extent.
