Robust Control of Regenerative Chatter in Orthogonal Cutting Process with Spindle Speed and Feed Rate Variation, M.Sc. Thesis Sharif University of Technology ; Vossoughi, Gholam Reza (Supervisor) ; Movahhedy, Mohammad Reza (Supervisor)
Abstract
During the turning operation, the interaction of the metal cutting process and machine tool causes a dynamic instability called self-excited vibration or chatter. Limited productivity rate, decrease in tool life, poor surface quality and noisy workplace are some adverse effects of the chatter vibration. Chatter suppression in machining processes results in more material removal rate, high precision and surface quality. In this thesis, two control strategies are developed to suppress chatter vibration in turning process including a worn tool. A single degree of freedom model of the turning process including tool wear is briefly described. In the first stage, a sinusoidal spindle speed...
