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 for the duration of
tool movements that are executed at feed rate. Dwell times are
included in the calculation 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 576).
