1.5 DIN PLUS: 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 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.
