Circumferential groove (SLOT2)

You can mill one or several circumferential slots of equal size on a full or pitch circle with the

"circumferential slot" cycle.

Please note that there is a minimum size for the milling cutter used to machine the

circumferential slot:

Annular groove

To create an annular groove, you must enter the following values for the "Number N" and

"Aperture angle α1" parameters:

Approach/retraction

1. At the height of the retraction plane, the tool approaches the center point of the semicircle

2. It is then inserted into the workpiece at the machining feedrate, allowing for the maximum

3. When the first circumferential groove is finished, the tool moves to the retraction plane at

4. The next circumferential groove is approached along a straight line or circular path and

5. The rapid traverse feedrate for positioning on a circular path is specified in a machine
