Functions for setting the datum
After probing you can set a new datum or transfer the captured values
to a datum or tool table.
Writing probed values to tables
The TNC writes the probed value to a table after the TRANSFER TO
TABLE soft key is pressed. You can choose a datum table (NAME.D)
as well as a tool table (NAME.T):
8 Select manual probing by pressing the TOUCH PROBE soft key.
8 Enter the name of the datum or tool table.
8 Enter the datum number or tool number.
8 Select the probing function and begin probing.
8 Press the TRANSFER TO TABLE soft key for the TNC to write the
probed value to the selected table.
Writing probed values to a table while a program is running
You can also write probed values to the TOOL table during program
run. Use miscellaneous function M109 to transfer the contents of the
Q parameters Q81 to Q84 into the table TOOL.T.
You can also use M108 to read the tool compensation values from the
TOOL table into parameters Q81 to Q84 (see also ”Q parameters for
the datum table: Q81 to Q84” on page 206).
