In some cases, the material we need to process has a certain degree of curvature. How to deal with it? This requires the projection engraving function of the woodworking engraving machine.
Projection engraving is to project the path onto the surface according to the vertical direction of the machined surface. It is mainly used to engrave or scribe on some materials with curvature, or to engrave some patterns. It can be imagined to use a beam of parallel light in a specified direction. Graphic, the shadow of the graph falling on the surface (plane) is the projection.
The arc surface projection engraving has three related parameters: retaining the original depth, closing the radius compensation, and transforming the original path. If you choose to retain the original depth, the projection path will retain the original depth change. This option can project the planar engraving path onto the surface. , to achieve surface processing. If you choose to turn off the radius compensation, you can speed up the calculation, but this will lead to lower precision of the sample processed by the wood engraving machine. If you choose to transform the original path, the arc-projection engraving does not generate a new tool path, but only complete Select the projection transformation of the path, the system does not change the order of the original path, and does not change the tool of the original path. After selecting this option, the tool selected by this operation is invalid.
