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 TNC takes the following into account for the time calculation:
 Traverse movements at feed rate
 Dwell times
 Machine dynamics settings (accelerations, filter settings, motion
control)
The time calculated by the TNC does not include rapid-traverse
movements and times depending on the individual machine tool (e.g.
tool change).
If you have switched the "calculate 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 190).
Activating the stopwatch function
 Shift the soft-key row until the soft-key for the
stopwatch functions appears
 Select the stopwatch functions
 Select the desired function by soft key, e.g. saving the

During the test run, the TNC resets the machining time as
soon as a new BLK form G30/G31 is evaluated.
