Programming
G2/G3 X… Y… Z…
I=AC(…) J=AC(…) K=AC(…)
Absolute center point and end point with reference to the
workpiece zero
Or
G2/G3 X… Y… Z… I… J… K…
Center point in incremental dimensions with reference to
the circle starting point
Or
G2/G3 X… Y… Z… CR=…
Circle radius CR= and circle end position in Cartesian
coordinates X..., Y..., Z...
Or
G2/G3 X… Y… Z… AR=…
Opening angle AR= end point in Cartesian coordinates
X..., Y..., Z...
Or
G2/G3 I… J… K… AR=…
Opening angle AR= center point at addresses I...,
J..., K...
Or
G2/G3 AP=… RP=…
Polar coordinates with the polar angle AP= and the polar
radius RP=
Or
CIP X… Y… Z… I1=AC(…)
J1=AC(…) K1=(AC…)
The intermediate point at addresses I1=, J1=, K1=
Or
CT X… Y… Z…
Circle through starting and end point and tangent
direction at starting point
Parameters
G2
Circular interpolation, CW
G3
Circular interpolation counterclockwise
CIP
Circular interpolation through intermediate point
CT
Circle with tangential transition defines the circle
X Y Z
End point in Cartesian coordinates
I J K
Circle center point in Cartesian coordinates in X, Y, Z direction
CR=
Circle radius
AR=
Opening angle
AP=
End point in polar coordinates, in this case the polar angle
RP=
End point in polar coordinates, in this case polar radius corresponding
to circle radius
I1= J1= K1=
Intermediate points in Cartesian coordinates in X, Y, Z direction
