Using touch probe functions with mechanical
probes or dial gauges

If you do not have an electronic 3-D touch probe on your machine, you
can also use all the previously described manual touch probe functions
(exception: calibration function) with mechanical probes or by simply
touching the workpiece with the tool.

In place of the electronic signal generated automatically by a 3-D touch
probe during probing, you can manually initiate the trigger signal for
capturing the probing position by pressing a key. Proceed as follows:

Select any touch probe function by soft key

Move the mechanical probe to the first position to be

captured by the TNC

Confirm the position: Press the actual-position-

capture soft key for the TNC to save the current
position

Move the mechanical probe to the next position to be

captured by the TNC

Confirm the position: Press the actual-position-

capture soft key for the TNC to save the current
position

If required, move to additional positions and capture

as described previously

Datum

: In the menu window, enter the coordinates of

the new datum, confirm with the SET DATUM soft
key, or write the values to a table (see "Writing the
measured values from touch probe cycles to datum
tables", page 295
, or see "Writing the measured
values from touch probe cycles to the preset table",
page 296)

Terminate the probing function: Press the END key
