When you cut a workpiece using a part program made from a part drawing,
you want 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, you establish the work
coordinate system by programming the distance between the desired zero
point of the work coordinate system and the zero point of the machine
coordinate system.
