The key of CNC is the selection of range and face.

[jingwang123]

The area of tool path processing is: the selected face within the selected range is the termination surface, and the principle is that all places where the tool can go down from the highest point to the lowest point. The selected face should preferably be a full face, while the boundary can only be the area to be machined. The distance of no face extension is less than half of the tool diameter. Because other faces have enough margin, they are automatically protected; It is better to extend the lowest line, because there is no R gong at the lowest point.
