"Circular slot pattern, lateral surface" unit
The unit machines a circular slot pattern in which the individual
features are arranged at a regular spacing on the lateral surface. 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: G792_Cir_Mant_C / Cycle: G792 (see page 350)

Pattern form
Q
Number of slots
ZM, CM Center point of pattern
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)
