The "Multiple edge" function is used when you want to mill a multiple
edge with any number of edges on the end face.
You can select from the following shapes with or without a corner
radius or chamfer:

Multiple edge

1. The tool approaches the starting point at rapid traverse at the
height of the retraction plane and adjusts to the safety clearance.
2. The tool traverses the multiple edge in a quadrant at machining
feed. The tool first executes infeed at machining depth and then
moves in the plane. The multiple edge is machined as a function of
the programmed machining direction (climb/conventional) in a
clockwise or counterclockwise direction.
3. When the first plane has been machined, the tool retracts from the
contour in the plane in a quadrant and then infeeds to the next
machining depth.
4. The multiple edge is traversed again in a quadrant. It repeats the
process until the depth of the multiple edge has been reached.
5. The tool moves back to the safety clearance at rapid traverse.
A multiple edge with more than two edges is circumnavigated
helically; with a single or double edge, each edge is machined
separately.
