Circular arc in YZ plane G182/G183-Geo
G182 and G183 define a circular arc in a contour of the YZ plane.
Parameters:
Y: Final point
Z: Final point
R: Radius
J: Center (in Y)
K: Center (in Z)
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)
W: Final point (polar angle; reference: workpiece datum)
PM: Center (polar radius; reference: workpiece datum)
WM: Center (polar angle; reference: workpiece datum)
AR: Start angle – tangential angle to rotary axis
AN: Final angle – tangential angle to rotary axis
Programming:
Y, Z: Absolute, incremental, modal or ?
J, K: Absolute or incremental
PZ, W, PM, WM: Absolute or incremental
ANi: Angle to the subsequent element
ARi: Angle to the previous element
End point must not be the starting point (no full
circle)
