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.
Machining time in the machine operating modes
