5.2 Contours 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 Diameter (pattern diameter)
A Starting angle—position of the first figure (reference: positive
X axis; default: 0°)
W Final 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)
0: Normal position—the figures are rotated about the circle
center (rotation)
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.
