G268 is a 5 axis G-Code used to define a tilted feature coordinate system relative to the working coordinate system. Canned cycles and G-codes work normally within the feature coordinate system. Before activating G268, G43 Tool Length Compensation, must be activated. However, the transformation from the working coordinate system to the feature coordinate system is performed independently from the tool length offset. Calling G268 only establishes the feature coordinate system. It does not cause motion in any axis. After calling G268 the current position of the spindle must be recalled. G269 is used to cancel G268 and revert back the WCS.
There are two ways to define a feature coordinate system using G268. The first is to command the B and C axis to the desired angle and specify only the feature coordinate system origin using G268. The feature coordinate system plane will be the plane normal to the spindle axis at the moment G268 is called.
|G99 + G268 is only supported for use with live tooling, not for use with the lathe spindle turning.|
