REFERENCE SYSTEMS
4.1 Reference points
A CNC machine needs the following origin and reference points defined :
• Machine Reference Zero or home. This is set by the manufacturer as the origin of the coordinate
system of the machine.
• Part zero or point of origin of the part. This is the origin point that is set for programming the
measurements of the part. It can be freely selected by the programmer, and its machine
reference zero can be set by the zero offset.
• Machine Reference point. This is a point on the machine established by the manufacturer around
which the synchronization of the system is done. The control positions the axis on this point,
instead of moving it as far as the Machine Reference Zero, taking, at this point, the reference
coordinates which are defined via the axis machine parameter "REFVALUE".

WPart zero
R Machine reference point
XMW, YMW, ZMW... Coordinates of the part zero
