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°
Approach/retraction
1. The tool approaches the center point of the semicircle at the end of the slot at rapid
2. Then, the tool enters the workpiece at machining infeed (taking into consideration the
