Manual Operation and Setup
14.7 Using 3-D touch probes
Select probing cycle
Select the Manual operation or Electronic
handwheel operating mode
Select the probing functions: Press the PROBING
FUNCTION soft key
Select the touch probe cycle: Press e.g. the
PROBING POS soft key, and the TNC displays the
associated menu on the screen
When you select a manual probing function, the
TNC opens a form displaying all data required.
The content of the forms varies depending on the
respective function.
You can also enter values in some of the fields. Use
the arrow keys to move to the desired input field.
You can position the cursor only in fields that can be
edited. Fields that cannot be edited appear dimmed.
Record measured values from the touch probe
cycles
The TNC must be specially prepared by the machine
tool builder for use of this function. Refer to your
machine manual.
After executing the respective selected touch probe cycle, the TNC
displays the WRITE LOG TO FILE soft key. If you press this soft key,
the TNC will record the current values determined in the active
touch probe cycle.
If you store the measuring results, the TNC creates the text file
TCHPRMAN.TXT. If you have not specified a path in the machine
parameter fn16DefaultPath (no. 102202), the TNC will save the
TCHPRMAN.TXT and TCHPRMAN.html files in the main directory
TNC:\.
When you press the WRITE LOG TO FILE soft key,
the TCHPRMAN.TXT file must not be active in the
Programming mode of operation. The TNC will
otherwise display an error message.
The TNC writes the measured values to the
TCHPRMAN.TXT or TCHPRMAN.html file. If you
execute several touch probe cycles in succession
and want to store the resulting measured values,
you must make a backup of the contents stored in
TCHPRMAN.TXT in between the individual cycles by
copying or renaming the file.
Format and content of the TCHPRMAN.TXT file are
preset by the machine tool builder.
