G102-Geo
Circular arc in front end contour G102-/G103-Geo
G102/G103 defines a circular arc in a front/end face contour. The
direction of rotation is visible in the help graphic.
Parameters
X, C: End point in polar coordinates (diameter, end angle)
XK,YK: End point in Cartesian coordinates
R:
Radius
I, J: Center in Cartesian coordinates
Q: Selection of intersection – default: 0
■ Q=0: Far intersection
■ Q=1: Near intersection
B: Chamfer/ rounding at end of circular arc
■ B no entry: tangential transition
■ B=0: no tangential transition
■ B>0: Radius of rounding
■ B<0: Width of chamfer
The end point may not be the same as the starting point (not a
full circle).
