Circular pattern on front/rear face G402-Geo
G402 defines a circular hole pattern or figure pattern on the front or
rear face. G402 is effective for the hole/figure defined in the following
block (G300 to 305, G307).
Parameters
Q Number of figures
K Pattern diameter
A Starting angle – position of the first figure; reference: XK axis;
(default: 0°)
W End angle – position of the last figure; reference: XK axis;
(default: 360°)
Wi Angle between 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)
XK Center in Cartesian coordinates
YK Center in Cartesian coordinates
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: See "Circular pattern
with circular slots" on page 220..
 The milling cycle (MACHINING section) calls the hole/
figure in the following block—not the pattern definition.
