When grinding a part using a part program made from a part drawing, it is
sometimes desirable to match the zero point on the coordinate system of
the part drawing with the zero point of the work coordinate system.
As shown in the illustrations in Figure 11.3, the work coordinate system is
established by programming the distance between the desired zero point of
the work coordinate system and the zero point of the machine coordinate
system.
