ICP programming | Contours in the XY plane
Centric polygon in XY plane
This function defines polygonal surfaces in the XY plane.
Reference data of XY plane:
ID: Contour
C: Spindle angle
IR: Limit diameter
Parameters of single surface:
Z: Reference edge
Q: No. of surfaces (Q >= 2)
K: Width across – inscribed circle diameter
Ki: Edge length
B: Breadth (reference: Reference dimension ZR)
B < 0: Surface in negative Z direction
B > 0: Surface in positive Z direction
You can switch between Edge length Ki and Width across K by
soft key.
You can use the Select reference plane function to determine the
Reference dimension ZR and the Limit diameter IR.

ICP generates the following:
The FRONT Y section code with the Limit diameter, Reference
dimension, and Spindle angle parameters. The section code is
omitted for nested contours.
a G308 with the Contour name parameter
A G477 with the parameters of the polygon
A G309
Soft key
Switch the field to the input of Width across K
