Datum management with the preset table
You should definitely use preset tables if:
n Your machine is equipped with rotary axes (tilting table
or swivel head) and you work with the tilted working
plan function
n
Your machine is equipped with a spindle-head changing
system
n Up to now you have been working with older TNC
controls with REF-based datum tables
n You wish to machine identical workpieces that are
differently aligned
Preset tables can contain any number of lines (datums).
To optimize the file size and the processing speed, you
should use only as many lines as you need for datum
management.
For safety reasons, new lines can be inserted only at the
end of the preset table.
