Circumferential groove (SLOT2)

Function
You can mill one or several circumferential slots of equal size on a full or pitch circle with the
"circumferential slot" cycle.
Tool size
Please note that there is a minimum size for the milling cutter used to machine the
circumferential slot:
● Roughing:
1⁄2 groove width W – finishing allowance UXY ≤ milling cutter diameter
● Finishing:
1⁄2 groove width W ≤ milling cutter diameter
● Edge finishing:
Finishing allowance UXY ≤ milling cutter diameter
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°
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
