HEIDENHAIN CNC PILOT 4290 97
Line segment in front-face/rear-face contour G101 Geo
Parameters
X:
End point in polar coordinates (diameter)
C: End point in polar coordinates (angular dimension)
XK,YK: End point in Cartesian coordinates
A: Angle to positive XK axis
B: Chamfer/rounding arc – transition to the next contour element.
Program the theoretical end point when entering a chamfer/
rounding.
■ B No input: Tangential transition
■ B=0: Nontangential transition
■ B>0: Radius of rounding
■ B<0: Width of chamfer
Q: Selection of intersection – default: 0. End point, if the line
segment intersects a circular arc.
■ Q=0: near intersection
■ Q=1: distance intersection
Programming
■ X, XK, YX: absolute, incremental, modal or ”?”
■ C: absolute, incremental or modal
G102 Geo
Circular arc on front/rear face G102/G103 Geo
Direction of rotation: see help graphic
Parameters
X:
End point in polar coordinates (diameter)
C: End point in polar coordinates (angular dimension)
XK,YK: End point in Cartesian coordinates
R: Radius
I, J: Center in Cartesian coordinates
Q: Selection of intersection – default: 0. End point, if the circular arc
intersects a circular arc.
■ Q=0: Far intersection
■ Q=1: Near intersection
