Parameters
G2 Travel on a circular path in clockwise direction
G3 Travel on a circular path in counterclockwise direction
X Y Z End point in Cartesian coordinates
I J K Circle center point in Cartesian coordinates
AR Aperture angle
TURN= Number of additional circle passes within the range 0 to
999
AP= Polar angle
RP= Polar radius
