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 approximate time that the TNC calculates from
the duration of tool movements. The time calculated by the TNC
cannot 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 “Dependent files” on page 593).
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.
