6.3 Contours in the YZ plane
Starting point of contour in YZ plane G180-Geo
G180 defines the starting point of a contour in the YZ plane.
Line segment in YZ plane G181-Geo
G181 defines a line segment in a contour of the YZ plane.
Parameters
Y Starting point of contour
Z Starting point of contour
Parameters
Y End point
Z End point
AN Angle to positive Z 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 entry: Tangential transition
 BR=0: No tangential transition
 BR>0: Rounding radius
 BR<0: Width of chamfer
Programming Y, Z: Absolute, incremental, modal or "?"
