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.
Note
A multi-edge with more than two edges is traversed helically; with a single or double
edge, each edge is machined separately.
Procedure
1. The part program or ShopMill program to be processed has been
created and you are in the editor.
3. Press the "Milling" softkey.
4. Press the "Multi-edge spigot" and "Multi-edge" softkeys.
The "Multi-edge" input window opens.

position

Single position
A polygon is milled at the programmed position (X0, Y0, Z0).
 Position pattern
Several polygons are milled at the programmed position pattern (e.g. pitch circle,
grid, line).
