Measuring the machining time

Program Run modes of operation

The timer counts and displays the time from program start to program
end. The timer stops whenever machining is interrupted.

Test run

The timer displays the time that the TNC calculates from the duration
of tool movements, including dwell times calculated by the TNC. The
time calculated by the TNC can only conditionally be used for
calculating the production time because the TNC does not account for
the duration of machine-dependent interruptions, such as tool change.

If you have switched the “find machining time” function on, you can
generate a file listing the usage times of all tools used in the program
(see “Tool usage test” on page 683).

Activating the stopwatch function
