1.2 Machine reference zero and part zero.
They are the references that the machine needs to work.
Machine reference zero (OM)
It is set by the manufacturer and it is the origin point of the axes.
Part zero (OP)
It is set by the operator. It is the part's origin point, used as
reference to program the movements. It may be preset
anywhere on the part.

1.3 Home search.
When the CNC is off, the axes may be moved manually or unintentionally. When that happens, the CNC loses the actual position
of the axes, that's why it is recommended (although not necessary) to do a "home search" when the turning the CNC on. With
this operation, the tool moves to a point set by the manufacturer and the CNC synchronizes its position assuming the
coordinates set by the manufacturer for that point, referred to machine reference zero.
NOTE: With the new feedback devices (distance-coded reference marks - Io -), it is possible to know the position of the axes
by just moving them a very short distance. This does away with the concept of machine reference.
Machine reference: It is the point to which the tool moves in a home search.
Turret reference: Point that moves with the turret. It is the point that moves in a home search.
Machine reference.

1.4 Travel limits.
This type of machines have two types of travel limits:
•Physical limits. They are set by the machine to prevent the carriages from going off its ways (cams and mechanical stops).
•CNC limits. They are set by the manufacturer at the CNC to prevent the carriages from running into the physical travel limits.
