ours in the YZ Plane
Circular arc G182/G183 Geo
G182/G183 defines a circular arc in a contour of the YZ plane. Direction
of rotation: See help graphic
Parameters
Y
End point (radius)
Z End point
J Center (Y direction)
K Center (Z direction)
R Radius
B Chamfer/rounding. Defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point.
„ No entry: Tangential transition
„ B=0: No tangential transition
„ B>0: Rounding radius
„ B<0: Chamfer width
Q Point of intersection. End point if the line segment intersects
a circular arc (default: 0):
„ For a transition to a line segment:
„ Q=0: Near point of intersection
„ Q=1: Far point of intersection
„ For a transition to a circular arc:
„ Q=0: Far point of intersection
„ Q=1: Near point of intersection
Programming
„ Y, Z: Absolute, incremental, modal or “?”
„ J, K: Absolute or incremental
„ End point must not be the starting point (no full circle).
