HEIDENHAIN SW 54843x-03 DIN Programming - Manual (Page 512)

512 DIN programming for the Y axis
6.2 Cont
ours in the XY plane
Single surface in XY plane G376-Geo
G376 defines a surface in the XY plane.
Centric polygon in XY plane G477-Geo
G477 defines polygonal surfaces in the XY plane.
Parameters
Z
Reference edge (default: "Z" from section code)
K Residual depth
Ki Depth
B Width (reference: reference edge Z)
 B<0: Surface in negative Z direction
 B>0: Surface in positive Z direction
I Limit diameter (as cutting limit and as reference for K/Ki)
 No input: "X" from section code
 "I" overwrites "X" from section code
C Spindle angle of surface normal (default: "C" from section code)
Whether the surface lies on the front face or rear side has
no effect on the evaluation of the algebraic sign for "width
B."
Parameters
Z
Reference edge (default: "Z" from section code)
K Width across flats (inscribed circle diameter)
Ki Edge length
B Width (reference: reference edge Z)
 B<0: Surface in negative Z direction
 B>0: Surface in positive Z direction
C Spindle angle of surface normal (default: "C" from section code)
Q Number of sides (Q >= 2)
I Limit diameter (as cutting limit)
 No input: "X" from section code
 "I" overwrites "X" from section code
Whether the surface lies on the front face or rear side has
no effect on the evaluation of the algebraic sign for "width
B."
