6.2 Cont
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 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.
