2.2 Approaching the reference point
You turning machine can be equipped with an absolute or incremental
path measuring system. An incremental path measuring system must
be calibrated after being switched on, but an absolute path measuring
system does not.
For the incremental path measuring system, all the machine axes
must therefore first approach a reference point, the coordinates of
which are known to be relative to the machine zero-point.
The sequence in which you must refer the axes is preset by the
machine manufacturer. The axes can also all approach the reference
point simultaneously, depending on the manufacturer’s settings.
Please also refer to the machine manufacturer's instructions.
During the reference point traversing, the feedrate override is in effect.
