Circular tapping pattern, lateral surface unit
This unit machines a circular tapping pattern on the lateral surface
of the workpiece.
Unit name: G73_Cir_Mant_C / cycle: G73
Further information: "Tapping G73", Page 376
Pattern form:
Q: Number of holes
ZM: Center of pattern
CM: Angle of pattern center
A: Start angle
Wi: End angle – Angle increment
K: Pattern diameter
W: Final angle
VD: Rotation dir. (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)
