Coupled model for simulating active inertial actuators in milling processes

In the last years, different active methods and devices have been proposed to suppress chatter vibrations. Among active control devices, inertial actuators have demonstrated their good behaviour in several studies. However, their dimensioning and tuning are not clear issues. This work proposes the utilization of a novel coupled model, based on experimental data, where the cutting process and the effect of an active inertial device are simulated in time domain.

In this way, the model permits to simulate different control strategies, control filters and actuators. The location of the actuator and the collocation or not of accelerometer can be taken into account, as well. In this work, the mathematical formulation of the model is developed, several applications are shown and, finally, its predictions are verified by means of real cutting operations.
