Distance between reference point
and workpiece holder is intrinsically
determined according to machines.
The distance between the reference
point and the end locator is intrinsically
determined according to machines.

Accordingly, if the start point is at the reference point and the point located
at the left lower side of the workpiece is presumed as the zero point of the
work coordinate system, tool position at the start point can be taught to
NC as a position in the work coordinate system by giving the following
command at the initial stage of programming.
