Single surface in XY plane G376-Geo
G376 defines a surface in the XY plane.
Parameters:
Z: Reference edge (default: Z from section code)
K: Residual depth
Ki: Depth
B: Breadth (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 and
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 or rear face has no
effect on the evaluation of the algebraic sign for Breadth
B.
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: Width across – inscribed circle diameter
Ki: Edge length
B: Breadth (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: No. of surfaces (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 or rear face has no
effect on the evaluation of the algebraic sign for Breadth
B.
