AR: Opening angle
TURN= : Number of additional circular passes in the range from 0 to 999
AP= : Polar angle
RP= : Polar radius
Note
G2 and G3 are modal.
The circular motion is performed in those axes that are defined by the specification of the
working plane.
Example

tions: Execute two full cir-
cles after the starting posi-
tion, then travel to end
point.
