In Example 11.6 and Figure 11.11, the offset entered for the G54 work
coordinate system has also shifted the G55 coordinate system. Any offsets
discussed in this section alter all of the work coordinate systems
(G54 - G59.3) at the same time.
To offset a work coordinate system an incremental amount from its zero
point, program a G52 block that includes the axis names and distances to
be offset.
G52 X__ Y__ Z__ ;
The above command offsets the current work coordinate system by the
axis values that follow the G52 command.
In Example 11.7, no axis motion takes place when the G52 block is
executed, however, the work coordinate system position values change.
See Figure 11.12.
