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:
Note
Using side mills and saws
When using a side mill (type 150) or a saw (type 151), the first infeed is selected so that the
top edge of the tool touches reference point Z0 exactly. At the end of the machining, the tool
is extracted completely from the blank spigot. In this way, an inner multi-edge can be produced.
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction plane
and is fed in to the safety clearance.
2. The tool traverses the multi-edge in a quadrant at machining feedrate. The tool first
executes infeed at machining depth and then moves in the plane. The multi-edge is
machined depending on the programmed machining direction (up-cut/down-cut) in a
clockwise or counterclockwise direction.
3. When the first plane has been machined, the tool retracts from the contour in a quadrant
and then infeed to the next machining depth is performed.
