Fanuc G68 Coordinate Rotation

G68 Coordinate Rotation

Fanuc G68 Coordinate Rotation G-Code makes it easy for cnc machinist to run a pattern of operations in a rotated angle.

In short: By designating a rotation angle with G68 in the program, actual machining will be performed on the rotated coordinate.

You can specify the Center-point (origin) and Angle-of-rotation, and whole the pattern of operation will be executed there.


G68 X…Y… R…


X,YCentre of rotation.
RAngle of rotation (R+ = Anti-clockwise).

If the X & Y values are not programmed with G68 Coordinate Rotation then the current tool position becomes the rotation pole center.

G91 Incremental Mode

The X, Y & R are established as incremental values if G68 is specified with a G91 code.

G69 Cancel Coordinate Rotation

The Rotation must be cancelled with G69 when finished.
