5.14 Contours in the XY plane
Centric polygon in XY plane
This function defines polygonal surfaces in the XY plane.
You can switch between edge length (Ki) and width across flats (K) by
pressing a soft key (see table at right).
You can find the reference dimension ZR and the limit diameter IR
with the "select reference plane" function (siehe Seite 425).
ICP generates:
 The FACE_Y section code with the parameters limit diameter,
reference dimension and spindle angle. The section code is omitted
for nested contours.
 A G308 with the parameter contour name.
 A G477 with the parameters of the polygon.
 A G309.
Soft key
Switches the field to entering the
width across flats K.
Reference data of the polygon
ID Contour name
C Spindle angle (position angle of the surface normal)
IR Limit diameter
Parameters of the polygon
Z Reference edge
Q Number of sides (Q>=2)
K Width across flats
Ki Length of edge
B Width (reference: reference dimension ZR)
 B<0: Surface in negative Z direction
 B>0: Surface in positive Z direction
