Shift values become valid immediately after they are set.
Setting a command (G50 or G92) for setting a coordinate system disables
the set shift values.
Example When G50 X100.0 Z80.0; is specified, the coordinate system
is set so that the current tool reference position is X = 100.0,
Z = 80.0 regardless of the shift values.
If the automatic coordinate system setting is performed by manual
reference position return after shift amount setting, the coordinate system
is shifted instantly.
Whether the shift amount on the X axis is diameter or radius value
depends on that specified in program.
When the actual position of the reference point is X = 121.0 (diameter),
Z = 69.0 with respect to the workpiece origin but it should be X = 120.0,
Z = 70.0, set the following shift values:
X=1.0, Z=–1.0
