A study on the chatter characteristics of the thin wall cylindrical workpiece

Abstract The purpose of this study was to analyze the chatter characteristics of a thin wall cylindrical workpiece. Initially, the structural dynamics of the workpiece were investigated, then the chatter phenomenon during the cutting experiment were observed. From the results, it was clear that the value of the stiffness coefficient of shell mode decreases rapidly when the ratio between the inner diameter and the wall thickness increases. In the meantime, the value of the damping ratio for shell mode was very small. The high value of dynamic compliance causes the shell mode to be easily excited.
