"Circular slot pattern, face" unit
The unit machines a circular slot pattern in which the individual
features are arranged at a regular spacing on the face of the
workpiece. The starting points of the slots correspond to the pattern
positions. You define the length and the position of the slots in the
unit. The slot width equals the diameter of the milling cutter.
Unit name: G791_Cir_Stirn_C / Cycle: G791 (see page 337)

Pattern form
Q
Number of slots
XM, CM Polar center point
XK, YK Cartesian center point
A Starting angle
Wi Angle increment
K Pattern diameter
W End angle
V Rotation direction (default: 0)
 VD=0, without W: Figures are arranged on a full circle
 VD=0, with W: Figures are arranged on the longer
circular arc
 VD=0, with Wi: The algebraic sign of Wi defines the
direction (Wi<0: clockwise)
 VD=1, with W: Clockwise
 VD=1, with Wi: Clockwise (algebraic sign of Wi has no
effect)
 VD=2, with W: Counterclockwise
 VD=2, with Wi: Counterclockwise (algebraic sign of Wi
has no effect)
