The reference point is a certain fixed point on the machine. It is defined
as the point, to which a tool can be moved easily by the reference point
return.
When setting a workpiece to be machined to general turret punch press,
the workpiece is held by the workpiece holders after positioning it by
applying the end face of the workpiece to the end locator and workpiece
holders mounted on the machine as illustrated below.

Generally, the distance between the reference point and the end locator as
well as the distance between the reference point and the workpiece holders
are intrinsically determined according to machines, and they are separated
from each other by a fixed distance.
