Sometimes the materials we need to process have a certain curvature. How to deal with this? This requires the use of the projection engraving function of the woodworking engraving machine. Projection engraving is based on the vertical direction of the processing surface Projecting a path onto a curved surface is mainly used to engrave or draw lines on some curved materials, or to carve some patterns. It can be imagined as illuminating the graphics with a beam of parallel light in a specified direction, and the graphics fall on the curved surface (plane) The shadow on the surface is the projection.

There are three relevant parameters for curved projection engraving: retaining the original depth, turning off 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 plane engraving path onto the curved surface to achieve curved surface processing. If you choose to turn off radius compensation, you can speed up the calculation, but this will cause the accuracy of the samples processed by the woodworking engraving machine to decrease.

If you choose to transform the original path, arc projection engraving will not generate a new tool path, but only complete the projection transformation of the selected path. The system will not change the order of the original path, nor will it change the tool of the original path. After selecting this option, The tool selected for this operation is invalid.
