Reference point
Refer to the above figure as an example.
The reference point is assumed as the start point of the tool. Assume that
the distance between the reference point and the end locator is 1000 mm,
and the left workpiece holder is mounted at a place distant from the end
locator by 200 mm.
In order to machine the next workpiece by the same program after
machining one workpiece, the start point of the tool must also be the
reference point to the next workpiece.
Accordingly, programming must be made to set the end point to the
reference point.

“The end point is the reference point.” means that the position of the end
point is just the same as the start point on the machine tool, and the
workpiece holder position is the start point, i.e., the position distant from
the end locator by 200 mm.
However, the left lower point of the workpiece, i.e., the zero point of the
work coordinate system, does not meet the end locator position, but it is
distant from the end locator by 300 mm in the –X direction.
