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 or polar angle)
CY End point as linear value; reference: unrolled reference
diameter
AN Angle to Z axis
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
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
PZ End point (polar radius)
AR Angle to Z axis (AR corresponds to AN)
R Length (polar radius; reference: last contour point)
Programming
 Z, CY: Absolute, incremental, modal or "?"
 C: Absolute, incremental or modal
 ARi: Angle to the previous element
 ANi: Angle to the subsequent element
 Program either Z, C or Z, CY.
