Research Abstract

This work deals with the development of the analytical method in order to predict the stability chart of regenerative chatter in spite of the change of the mechanical transfer characteristics, the cutting condition and the cutting stiffness. The stability chart of regenerative chatter was predicted by the proposed analytical method with the hybrid model composed of the tool and spindle system modeled by continuum model and the workpiece model. It was confirmed that the stability chart of regenerative chatter predicted by the eigenvalue analysis coincided well with the experimental result.
