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.
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.
4. The multi-edge is traversed again in a quadrant. This process is repeated until the depth
of the multi-edge has been reached.
5. The tool retracts to the safety clearance at rapid traverse.
