Writing the measured values from touch probe
cycles in the preset table

With the ENTER IN PRESET TABLE soft key, the TNC can write the

values measured during a probe cycle in the preset table. The

measured values are then stored referenced to the machine-based

coordinate system (REF coordinates). The preset table has the name

PRESET.PR, and is saved in the directory TNC:\.

Select any probe function

Enter the desired coordinates of the datum in the appropriate input

boxes (depends on the touch probe cycle being run)

Enter the datum number in the Number in table: input box

Press the ENTER IN PRESET TABLE soft key. The TNC saves the

datum in the preset table under the entered number

Use this function if you want to save measured values in

the machine-based coordinate system (REF coordinates).

If you want to save measured values in the workpiece

coordinate system, press the ENTER IN DATUM TABLE

soft key (see "Writing the measured values from touch

probe cycles in datum tables" on page 491).

Danger of collision!

Note that during an active datum shift the TNC always

bases the probed value on the active datum (or on the

datum most recently set in the Manual operating mode),

although the datum shift is included in the position display.

If you overwrite the active datum, the TNC shows a

warning. If you really want to overwrite it, press the ENT

key. If not, press the NO ENT key.
