【Abstract】 octave-mode and 5-octave-mode generative chatter models of 4-H Cold Rolling Mills are studied, and stability analysis of chatter models due to negative damping is given. Subsequently, the unified theory of stability analysis of regenerative chatter is proposed. Finally, for more detailed understanding of the regenerative chatter phenomena and unified chatter theory, industrial investigations proceed in practice and a simulator is developed.更多还原
