4.8 Lateral Surface Contours
Circular pattern on lateral surface G412-Geo
G412 defines a circular hole or figure pattern on the lateral surface.
G412 is effective for the hole/figure defined in the following block
(G310 to 315, G317).
Parameters
Q Number of figures
K Pattern diameter
A Starting angle—position of the first figure; reference: Z axis;
(default: 0°)
W Final angle—position of the last figure; reference: Z axis
(default: 360°)
Wi Angle between figures
V Direction—orientation (default: 0)
V=0, without W: Figures are arranged on a full circle
V=0, with W: Figures are arranged on the longer circular arc
V=0, with Wi: The algebraic sign of Wi defines the direction
(Wi<0: clockwise)
V=1, with W: Clockwise
V=1, with Wi: Clockwise (algebraic sign of Wi has no effect)
V=2, with W: Counterclockwise
V=2, with Wi: Counterclockwise (algebraic sign of Wi has no
effect)
Z Center of pattern
C Center of pattern (angle)
H Position of the figures (default: 0)
H=0: Normal position; the figures are rotated about the circle
center (rotation)
H=1: Original position; the position of the figures relative to
the coordinate system remains unchanged (translation)
Program the hole/figure in the following block without a
center. Exception: circular slot: see “Circular pattern
with circular slots” on page 204.
The milling cycle (MACHINING section) calls the hole/
figure in the following block—not the pattern definition.
