Measurement of machining time
Machining time in the Test Run mode of operation
The control calculates the duration of the tool movements and
displays this as machining time in the test run. The control takes
feed movements and dwell times into account.
The time calculated by the control can only conditionally be used
for calculating the production time because the control does not
account for machine-dependent times, such as tool change.
The machining times shown for milling/turning
operations in the simulation do not correspond to the
actual machining times.
Machining time in the machine operating modes
Time display from program start to program end. The timer stops
whenever machining is interrupted.
