Multi-edge (CYCLE79)

Function
You can mill a multi-edge with any number of edges with the "Multi-edge" cycle.
You can select from the following shapes with or without a corner radius or chamfer:
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
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.

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