Additive rotation with AROT X... Y... Z...
The WCS is rotated further around the specified axes through the programmed angles of
rotation.

Rotation of the working plane
During a rotation using ROT/AROT, the working plane (G17, G18, G19) also rotates.
Example: Working plane G17
The WCS is positioned on the top surface of the workpiece. Using offset and rotation, the
coordinate system is moved to one of the side faces. Working plane G17 also rotates. In this
way, traversing motions can still be programmed in the G17 plane via X and Y and infeeds via
Z.
