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:
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.

Description
The positions refer to the reference point:
Reference point X – (for single position only)
Reference point Y – (for single position only)
Reference point Z
Diameter of circular spigot
Depth in relation to Z0 (abs or inc) - (only for ∇ and ∇∇∇)
Chamfer width for chamfering - (for chamfering only)
Insertion depth of tool tip (abs or inc) - (for chamfering only)
Maximum depth infeed - (only for ∇ and ∇∇∇)
Plane finishing allowance (spigot diameter) - (only for ∇ and ∇∇∇)
Depth finishing allowance (spigot base) - (only for ∇ and ∇∇∇)
