Datum management with the preset

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, only use as many

rows as you need to manage your datums.

For safety reasons, new lines can be inserted only at the end of the

preset table.
