Measurement of machining time

Machining time in the Test Run operating mode

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 determined by the control is only of limited value for

calculating the machining time because it does not take any

machine-dependent time intervals (e.g., for tool changes) into

consideration.

The machining times determined using the graphic

simulation do not correspond to the actual machining

times. Reasons for this during combined milling-turning

operations include the switching of operating modes.
