- Title of Paper:Active chatter suppression for milling process with sliding mode control and electromagnetic actuator
- Journal:Mechanical Systems and Signal Processing
- Summary:Milling chatter is a major factor limiting the machining efficiency and imposing poor surface finishes and even machine tool damage. This research presents a scheme for active milling chatter suppression with sliding mode control and electromagnetic actuator. The modeling of whole active chatter control system for milling process is presented, in which the model of electromagnetic actuator is considered. In addition, the stable components in the state variables caused by static milling force are ignored in the presented model. Then, an active sliding mode controller is presented, in which a dynamic output feedback sliding surface is introduced and the velocity state is not needed in the closed-loop feedback. The time delay item in the model are considered as disturbance, which makes the controller design easier. A designed spindle system integrated with electromagnetic actuator is also presented in this research. Simulation results show that the chatter-free domain is significantly improved in a wide spindle speed range. Milling experiments are also performed on the developed spindle system, and the experimental results illustrate that the milling chatter can be well suppressed with the presented scheme.
