In Figure 11.4, the machine coordinate system was defined by declaring
the fixed position machine home as the point X=-2., Z=-3. Then the G54
work coordinate system zero point is defined by the coordinates X=2, Z=3
in the machine coordinate system.
Coordinate positions in a part program are manipulated as coordinate
values in the default work coordinate system unless another coordinate
system is selected by programming G54-G59.3.
