Full circle The circumferential slots are positioned around a full circle. The slot spacing is
uniform and is calculated by the control.
Pitch circle The slots are positioned around a pitch circle. The slot spacing can be determined on
the basis of angle α 2.
The positions refer to the center point:
X0 Position in the X direction, abs. or inc.
Y0 Position in the Y direction, abs. or inc.
Z0 Workpiece height, abs. or inc.
W Slot width
R Radius of circumferential slot
α 0
Angle of rotation in relation to X axis
α 1 Angle of aperture of a slot
α 2 Advance angle (for pitch circle only)
N Number of slots
Z1 Depth of the slot, relative to Z0 (not for chamfer)
DZ Max. depth infeed (Z direction) (not for chamfer)
FS Chamfer width (for chamfer only), inc.
ZFS Insertion depth tool tip (for chamfer only), abs. or inc.
UXY Finishing allowance in XY plane (edge of slot) (not for chamfer)
Positioning Linear: Next position is approached linearly at rapid traverse.
Circular: Next position is approached at the programmed feedrate FP along a circular
path.
FP Feed for positioning on a circular path
