Recording the values measured in a probe cycle (not
TNC 410)
The TNC must be specially prepared by the machine tool
builder for use of this function. Refer to your machine
tool manual.
After executing any selected touch probe cycle, the TNC displays
the soft key PRINT. If you press this soft key, the TNC will record the
current values determined in the active probe cycle. You can then
use the PRINT function in the menu for setting the data interface
(see ”13 MOD Functions, Setting the Data Interface”) to define
whether the TNC is to
■
print the measuring result,
■
store the measuring results on the TNC’s hard disk, or
■
store the measuring results on a PC.
If you store the measuring results, the TNC creates the ASCII file
%TCHPRNT.A (see figure at top right). Unless you define a specific
path and interface in the interface configuration menu, the TNC will
store the %TCHPRNT file in the main directory TNC:\ .
When you press the PRINT soft key, the %TCHPRNT.A
file must not be active in the Programming and Editing
mode of operation. The TNC will otherwise display an
error message.
The TNC stores the measured data in the %TCHPRNT.A
file only. If you execute several touch probe cycles in
succession and want to store the resulting measured
data, you must make a backup of the contents stored in
%TCHPRNT.A between the individual cycles by copying
or renaming the file.
Format and contents of the %TCHPRNT file are preset
by the machine tool builder.
Writing the values from probe cycles in datum
tables (not TNC 410)
Using the ENTER IN DATUM TABLE soft key, the TNC can write the
values measured during a probe cycle in a datum table:
ú
Select any probe function
ú
Enter the name of the datum table (complete path) in the datum
table input box and confirm with ENT
ú
Enter the number of the datum in the Datum number = input box
and confirm with ENT
ú
Press the ENTER IN DATUM TABLE soft key. The TNC writes the
data into the indicated datum table.
