Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction
2. The tool traverses the multi-edge in a quadrant at machining feedrate. The tool first
3. When the first plane has been machined, the tool retracts from the contour in a quadrant
4. The multi-edge is traversed again in a quadrant. This process is repeated until the depth
5. The tool retracts to the safety clearance at rapid traverse.

machined depending on the programmed machining direction (up-cut/down-cut) in a
clockwise or counterclockwise direction.

Note
A multi-edge with more than two edges is traversed helically; with a single or double
edge, each edge is machined separately.
