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 648).
Activating the stopwatch function
Shift the soft-key rows until the TNC displays the following soft keys
with the stopwatch functions:
Stopwatch functions Soft key
Enable (ON) or disable (OFF) the "measure the
machining time" function.
Store displayed time
Display the sum of stored time
and displayed time
Clear displayed time
The soft keys available to the left of the stopwatch
functions depend on the selected screen layout.
During the Test Run, the TNC resets the machining time
as soon as a new BLK FORM is evaluated.
