Linear pattern in XY plane G471-Geo
G471 defines a linear pattern in the XY plane. G471 is effective for the
hole or figure defined in the following block (G370 to G375, G377).
Parameters
Q
Number of figures
X 1st point of pattern (radius)
Y 1st point of pattern
I End point of pattern (X direction; radius)
J End point of pattern (Y direction)
Ii Distance in X direction between two figures
Ji Distance in Y direction between two figures
A Position angle of longitudinal axis of pattern (reference:
positive X axis)
R Length (overall length of pattern)
Ri Pattern distance (distance between two figures)
Programming notes
 Program the hole/figure in the following block without a
center.
 The milling cycle (MACHINING section) calls the hole/
figure in the following block—not the pattern definition.
