Line segment in front/rear face contour G101-
Geo
G101 defines a line segment in a contour on the front face/rear face.
Parameters
X
End point in polar coordinates (diameter)
C End point in polar coordinates (angular dimension)
XK End point in Cartesian coordinates
YK End point in Cartesian coordinates
AN Angle to positive XK axis
Q Point of intersection. End point if the line segment intersects a
circular arc (default: 0):
 0: Near point of intersection
 1: Far point of intersection
BR Chamfer/rounding. Defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point.
 No input: Tangential transition
 BR=0: No tangential transition
 BR>0: Radius of rounding
 BR<0: Width of chamfer
AR Angle to positive XK axis (AR corresponds to AN)
R Length (polar radius; reference: last contour point)
Programming
 X, XK, YX: Absolute, incremental, modal or "?"
 C: Absolute, incremental or modal
 ARi: Angle to the previous element
 ANi: Angle to the subsequent element
