G68.2 Inclined plane, tilted work plane
Mazak (EIA) G-code · Mill
Defines a tilted work plane for 3 plus 2 machining on Variaxis or Integrex. The plane origin is X Y Z and the tilt is given as Euler angles I J K. Then G53.1 turns the tool to be normal to the plane.
Verify on your machine. This entry could not be fully checked against the maker manual. Check your machine manual before you run it.

I J K | Euler angles of the plane, in degrees |
How it works
Modal. Cancel with G69.
Example program
G68.2 X0. Y0. Z0. I0. J30. K0. (TILT PLANE 30 DEG)
G53.1 (ROTARIES MOVE TOOL NORMAL TO PLANE)
G43 H09 Z2. (LENGTH OFFSET ON TILTED PLANE)
…
The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Cancel with G69 before G28. Users report G28 overtravel alarms with G68.2 still active.
- Check how the control and the CAM post handle tool length with G53.1 before cutting.
