Circular arc in lateral surface contour G112-/
G113-Geo
G112/G113 defines a circular arc in a lateral-surface contour. Direction
of rotation: See help graphic
Parameters
Z
End point
C End point (end angle)
CY End point as linear value; reference: unrolled reference
diameter
R Radius
K Center point in Z direction
W Angle of the center point
J Angle of the center point as a linear value
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 circular arc intersects a line
segment or another circular arc (default: 0):
 0: Near point of intersection
 1: Far point of intersection
Programming
 Z, CY: Absolute, incremental, modal or "?"
 C: Absolute, incremental or modal
 K, J: Absolute or incremental
 Program either Z–C or Z–CY, and either K–W or K–J
 Program either center or radius
 For radius: Only arcs <= 180° are possible
