4.8 Lateral surface contours
Starting point of lateral surface contour G110-Geo
G110 defines the Start point of a lateral surface contour.
Parameters:
Z: Start point
C: Start angle (polar angle)
CY: Start point as linear value (reference: unrolled Reference
diameter)
PZ: Start point (polar radius)
Program either Z, C or Z, CY.
Line segment in a lateral surface contour G111-Geo
G111 defines a line segment in a lateral-surface contour.
Parameters:
Z: Final point
C: End angle
CY: Final point as linear value (reference: unrolled Reference
diameter)
AN: Angle to positive Z axis
Q: Intersect. pt. or Final point if the line segment intersects a
circular arc (default: 0)
0: Near point of intersection
1: Far point of intersection
BR: Chamf./round. – defines the transition to the next contour
element
When entering a Chamf./round., program the theoretical end
point.
No entry: Tangential transition
BR = 0: No tangential transition
BR > 0: Rounding radius
BR < 0: Width of chamfer
PZ: Final point (polar radius; reference: workpiece datum)
AR: Incr.angle to foregoer ARi (AR corresponds to AN)
R: Line length
Programming:
Z, CY: Absolute, incremental, modal or ?
C: Absolute, incremental or modal
ARi: Angle to the previous element
ANi: Angle to the subsequent element
