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-G375, G377).
Parameters:
Q: Number of figures
K: Diameter – pattern diameter
A: Start 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: Final angle – 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 W: The algebraic sign of Wi defines the direction
(W < 0: clockwise)
V = 1, with W: Clockwise
V = 1, with W: Clockwise (algebraic sign of W has no effect)
V = 2, with W: Counterclockwise
V = 2, with W: Counterclockwise (algebraic sign of W has no
effect)
X: Center of pattern (radius)
Y: Center of pattern
H: 0=Normal position – 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)
Programming notes:
Program the hole or figure in the following block
without a center. Exception: circular slot
Further information: "Circular pattern with circular
slots", Page 274
The milling cycle (MACHINING section) calls the
hole/figure in the following block—not the pattern
