The local coordinate system is set with the G52 command, and the program commands, etc.,
are issued with the local coordinate system.
With this function, the set local coordinate system is canceled, and the program commands,
etc., use the workpiece coordinate system which has W1 as the zero point. The canceled local
coordinate system is only the selected workpiece coordinate system.

The workpiece coordinate system shifts with the G92 command, and the distance between
W1' and the present position is set as the present position of the workpiece coordinate system.
This function returns the shifted workpiece coordinate zero point to W1, and sets the distance
from W1 to the present position as the workpiece coordinate system's present position. This is
valid for all workpiece coordinate systems.
