2.3.1 Origins of the reference systems
The position of the different reference systems is determined by their
respective origin points.
O
M
Machine zero
It is the origin point of the machine reference system, set by the
machine manufacturer.
O
F
Fixture zero
It is the origin point of the fixture reference system being used. Its
position is defined by the operator by using the "fixture offset" and is
referred to machine zero.
The "fixture offset" may be set by program or from the CNC's front
panel, as described in the Operating Manual.
O
W
Part zero
It is the origin point of the reference system of the part (workpiece).
Its position is set by the operator using the "zero offset" and is referred:
• To the fixture offset, if the fixture reference system is active. When
changing the fixture reference system, the CNC updates the part
zero position by referring to the new fixture zero point.
• To the machine zero point (home), if the fixture reference system
is NOT active. When activating the fixture reference system, the
CNC updates the part zero position by referring it to the fixture zero
point.
The "zero offset" may be set from the program or from the CNC front
panel as described in the Operating Manual.
Zero offset when:
(A) The fixture reference system is deactivated.
(B) The fixture reference system is activated.
