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
(G310.0.315, G317).
Parameters
Q Number of figures
K Pattern diameter
A Starting angle – position of the first figure; reference: Z axis;
(default: 0°)
W End 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 169.
„ The milling cycle (MACHINING section) calls the hole/
figure in the following block—not the pattern definition.
