On this issue, there are generally the following methods for engraving surface processing stratification:
1. Contour layering method: According to the design requirements, the surface is divided into several equal layers, and then processed layer by layer according to the hierarchical order.
2. Equal layering method: according to the surface curvature of the surface and the required accuracy, the surface is divided into several equal layers, and then processed layer by layer according to the hierarchical order.
3. Adaptive layering method: According to the shape complexity and processing accuracy requirements of the surface, the surface is divided into different levels adaptively, and then processed layer by layer according to the hierarchical order.
4. Tool path stratification method: according to the diameter and cutting depth of the tool, the surface is divided into several layers, and then processed layer by layer according to the tool path.
Each of the above methods has its advantages and disadvantages, and the appropriate layering method can be selected according to the actual situation.
Cut layers from bottom to top starting below the middle of the surface
