This function is used to compensate for the difference between the
programmed workpiece coordinate system and the actual workpiece
coordinate system. The measured offset for the origin of the workpiece
coordinate system can be input on the screen such that the command
values match the actual dimensions.
Selecting the new coordinate system matches the programmed coordinate
system with the actual coordinate system.
