Datum management with the preset
table

Note

You should definitely use the preset table if:

Your machine is equipped with rotary axes (tilting

table or swivel head) and you work with the

function for tilting the working plane
Your machine is equipped with a spindle-head

changing system
Up to now you have been working with older TNC

controls with REF-based datum tables
You wish to machine identical workpieces that are

differently aligned

The preset table 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 preset management.
For safety reasons, new lines can be inserted only at the end of the

preset table.
