4.3 Basic Contour Elements
Line segment in a contour G1-Geo
G1 defines a line segment in a turning contour.
Example: G1-Geo
Parameters
X Final point of contour element (diameter value)
Z Final point of contour element
AN Angle to rotary axis (for angle direction see help graphic)
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

elements” on page 181)
