The control has a feature (G68) that can rotate the work coordinate system.
There is also a feature called External Part Rotation which rotates all work
coordinate systems by simulating a rotation of the machine coordinate
system. Rotating the coordinate systems can prove to be useful when
cutting a part that contains symmetrical geometries (see Figure 13.1).
