Eccentric polygon on front/rear face G307-Geo
G307 defines a polygon in a contour on the front face/rear face.
Linear pattern on front/rear face G401-Geo
G401 defines a linear hole pattern or figure pattern on the front or rear
face. G401 is effective for the hole/figure defined in the following
block (G300 to 305, G307).
Parameters
XK Center in Cartesian coordinates
YK Center in Cartesian coordinates
Q Number of edges (Q > 2)
A Angle of a polygon edge to XK axis (default: 0°)
K Edge length
„ K>0: Edge length
„ K<0: Inscribed circle diameter
B (Height) width
R Chamfer/rounding arc (default: 0°)
„ R>0: Radius of rounding arc
„ R<0: Chamfer width
P Depth/height (default: “P” from G308)
„ P<0: Pocket
„ P>0: Island
Parameters
Q Number of figures (default: 1)
XK Starting point in Cartesian coordinates
YK Starting point in Cartesian coordinates
I End point in Cartesian coordinates
J End point in Cartesian coordinates
A Angle of longitudinal axis to XK axis (default: 0°)
R Total length of pattern
Ri Distance between figures (pattern distance)
„ 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.
