Line segment in a lateral surface contour G111-
Geo
G111 defines a line segment in a lateral-surface contour.
Parameters
Z
End point
C End point (end angle)
CY End point as linear value; reference: unrolled reference
diameter
AN Angle to Z axis
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
Q Point of intersection. End point if the line segment intersects a
line (default: 0):
 Q=0: Near point of intersection
 Q=1: Far point of intersection
Programming
 Z, CY: Absolute, incremental, modal or "?"
 C: Absolute, incremental or modal
 Program either Z–C or Z–CY
