What's the type of wood laser engraving?

According to different processing methods of laser engraving of wood materials, laser engraving of wood materials can be divided into the following three categories:
Cutting and engraving
It uses the cutting method to process the required pattern on the surface of the wooden material, that is, first decompose the pattern into several line forms, and then use laser to cut these lines, and then obtain the pattern represented by the cutting line.
Concave carving
The pattern part is cut away, and the peripheral part of the pattern is left as it is. There are two cases here. The first case is the same cutting force for each point on the pattern. The engraved pattern is mainly reflected by the outline shape. The second case is based on the distribution of the light and dark and contrast of the pattern. The "dark" part of the pattern is cut more, and the "bright" part of the pattern is cut less or not. The former is suitable for engraving characters, animals, plants and other patterns that are mainly based on appearance, while the latter is more suitable for engraving patterns with details such as facial expressions of characters.
Punch engraving
Contrary to concave die engraving, this engraving process only cuts the material around the pattern, and the cutting force is the same at each point, but the material of the pattern itself is not cut. This engraving method is suitable for the expression of text, graphic outline, etc. In the latter two engraving methods, the method of material removal is that each time the laser head walks on the cut surface, a linear groove is cut, and then the next line is cut after moving a small distance. Usually the distance between the two slots can be 0.05-0.5mm. In this way, multiple linear cuts are used to achieve the purpose of removing the area-forming material required by these two engraving forms. Of course, in the second form of concave die engraving, the size of the groove, especially the depth of the groove, will change as needed on the same cutting line.
