10.6.4 Circular interpolation with opening angle and center point (G2/G3, X... Y... Z.../
I... J... K..., AR)
The circular motion is described by:
● The opening angle AR = and
● The end point in Cartesian coordinates X, Y, Z or
● The circle center at addresses I, J, K
Syntax
G2/G3 X... Y... Z... AR=
G2/G3 I... J... K... AR=
Meaning
