4.4 Coordinate preset and zero offsets
The CNC allows you to carry out zero offsets with the aim of using coordinates related to the plane
of the part, without having to modify the coordinates of the different points of the part at the time
of programming.
The zero offset is defined as the distance between the part zero (point of origin of the part) and the
machine zero (point of origin of the machine).
M Machine zero
W Part zero
This zero offset can be carried out in one of two ways :
Via Function G92 (coordinate preset). The CNC accepts the coordinates of the programmed
axes after G92 as new axis values.
Via the use of zero offsets (G54 ... G59, G159N1 ... G159N20); the CNC accepts as a new part
zero the point located relative to machine zero at the distance indicated by the selected table(s).
Both functions are modal and incompatible, so if one is selected the other is disabled.
There is, moreover, another zero offset which is governed by the PLC. This offset is always added
to the zero offset selected and is used (among other things) to correct deviations produced as a
result of expansion, etc.
