ours in the XY Plane
Circular pattern in XY plane, G472 Geo
G472 defines a circular pattern in the XY plane. G472 is effective for
the figure defined in the following block (G370 to G375, G377).
Parameters
Q
Number of figures
K Pattern diameter
A Starting angle—position of the first figure; reference: positive
X axis (default: 0°)
W End angle—position of the last figure; reference: positive X
axis; (default: 360°)
Wi Angle between two 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)
X Center of pattern (radius)
Y Center of pattern
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.
„ The milling cycle (MACHINING section) calls the hole/
figure in the following block—not the pattern definition.
