Abstract

In this paper, a mathematic model is established to descript the dynamics of milling processes. To control the chatter during the milling processes, a feedback controller is designed by employing the robust mixed sensitivity method to achieve robust disturbance rejection and stabilization. Numerical simulations and cutting experiments are carried out to verify the efficiency. Results indicate that the controller works well in chatter suppression and robust disturbance rejection. At the same time, the control effectiveness aimed at relative vibration between cutter and workpiece and either cutter vibration or workpiece vibration is compared.
