HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 14)

Y Axis 14
2.2.1
Contours
in
the
XY
Plane
(Front
and
Back)
Single surface G376 Geo
G376 defines a surface in the XY plane.
Parameters
Z: Reference edge – no entry: ”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: Area diameter
■ No entry: ”X” from the section code.
■ ”I” overwrites ”X” from section code.
C: Angular position of surface – no entry: ”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.”
Centric polygon G477 Geo
G477 defines polygonal surfaces in the XY plane.
Parameters
Z: Reference edge – no entry: ”Z” from section code
K: Inside diameter (width across flats)
Ki: Length of side
B: Width (reference: reference edge Z)
■ B<0: Surface in negative Z direction
■ B>0: Surface in positive Z direction
C: Angular position of surface – no entry: ”C” from section
code
Q: Number of sides (Q ‡ 2)
I: Area diameter
■ No entry: ”X” from the 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.”
