CNC 8070
(SOFT V02.0X)
ORIGIN SELECTION
With this CNC, it is possible to program movements in the machine
reference system or apply offsets in order to use reference systems
referred to the fixtures or the part without having to change the
coordinates of the different points of the part in the program.
There are three types of offsets:
• Fixture offset.
• Zero offset.
• PLC offset.
Several offsets may be active at the same time. In this case, the
coordinate system being used will be defined by the sum of the active
offsets.
Fixture offset
A fixture offset is defined as the distance between the machine
reference zero and the fixture zero.
On machines using several fixtures, this offsets allows selecting the
particular fixture to be used.
Zero offset
A zero offset is defined as the distance between the fixture zero and
the part zero. If the fixture zero is not active (no fixture offset), the zero
offset is measured from machine zero.
The zero offset may be set in two ways:
• By presetting a coordinate, the CNC assumes the programmed
coordinates as the current position of the axes.
• By using absolute or incremental zero offsets, the CNC assumes
the new part zero set by the selected offset.
Zero offset when the fixture offset is zero.
