CAUTION: G92 offsets are global. Changing from one
coordinate system to another does not cancel the offset. Do not
specify a change in coordinate systems (G54-G59.3) unless the
effects of the offset have been considered.
Example 11.6 shows the effect of changing work coordinate systems while
the G92 offset is active.
