4.8 Lateral Surface Contours
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 Final point
C Final point (final angle)
CY Final 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
