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°
240
Description
The following insertion modes can be selected:
Centered G0
•
Approach of reference point shifted by the amount of the safety clearance with
G0
Centered: Insert vertically in longitudinal groove center:
•
The tool is inserted to infeed depth in the pocket center.
Note: This setting can be used only if the cutter can cut across center.
Oscillation: Insert with oscillation along center axis of longitudinal groove:
•
The cutter center point oscillates along a linear path until it reaches the depth
infeed. When the depth has been reached, the path is traversed again without
depth infeed in order to remove the slope caused by insertion.
Maximum insertion angle - (for insertion with oscillation only)
Depth infeed rate - (for insertion in center only)
1⁄2 groove width W – finishing allowance UXY ≤ milling cutter diameter
1⁄2 groove width W ≤ milling cutter diameter
