Multi-edge (CYCLE79)

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.

machined depending on the programmed machining direction (up-cut/down-cut) in a

clockwise or counterclockwise direction.

of the multi-edge has been reached.

A multi-edge with more than two edges is traversed helically; with a single or double

edge, each edge is machined separately.
