Circumferential groove (SLOT2)

Function
You can mill one or several circumferential grooves of equal size on a full or pitch circle with
the "circumferential groove" cycle.
Tool size
Please note that there is a minimum size for the milling cutter used to machine the
circumferential groove:
● Roughing:
● Finishing:
● Edge finishing:
Annular groove
To create an annular groove, you must enter the following values for the "Number N" and
"Aperture angle α1" parameters:
N = 1
α1 = 360°
