Measurement of machining time
Program Run, Single Block and Program Run, Full Sequence
operating modes
The timer counts and displays the time from program start to
program end. The timer stops whenever machining is interrupted.
Test Run operating mode
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.
