Starting point of contour G180 Geo
G180 defines the starting point of a contour in the YZ plane.
Linear element G181 Geo
G181 defines a line segment in a contour of the YZ plane.

Parameters
Y
End point
Z End point
A Angle to positive Z axis
B Chamfer/rounding. Defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point.
„ No entry: Tangential transition
„ B=0: No tangential transition
„ B>0: Rounding radius
„ B<0: Chamfer width
Q Point of intersection. End point if the line segment intersects
a circular arc (default: 0):
„ Q=0: Near point of intersection
„ Q=1: Far point of intersection
Programming Y, Z: Absolute, incremental, modal or “?”
