4.8 Circular interpolation with arc angle and center point (G2/G3, AR=)
Programming a circle with arc angle and center point or end point
The circular movement is defined by:
• The arc angle AR = and
• the end point in Cartesian coordinates X, Y, Z or
• the circle center point at addresses I, J, K
Programming
G2/G3 X... Y... Z... AR=
Or
G2/G3 I... J... K... AR=

Circular interpolation clockwise
Circular interpolation counterclockwise
End point in Cartesian coordinates
Circle center point in Cartesian coordinates (in X, Y, Z
direction)
The identifiers have the following meanings:
I: Coordinate of the circle center point in the
direction
J: Coordinate of the circle center point in the
direction
K: Coordinate of the circle center point in the
direction
Arc angle, value range 0° to 360°
Absolute dimensions (non-modal)
