✦ Synopsis

AlmtnctmTbe vibration characteristics and the vibration direction angle between the beam mode and shell mode of the three-jaw clamped thin.wall cylindrical workpiece will change accordin 8 to the relative position of the cutting tool to the chucking jaws. This will induce parametric vibration and cause the chatter characteristics of a thin-wall cylindrical workpiece to become more complicated than those of a solid workpi¢ce. In this study, the three-jaw damped thin-wall cylindrical workpiece was considered as a parametrically excited vibration system. Initially, the relationship between the parametric vibration and the workpiece system structure was investigated, and then the equivalent stability cutting depth of the thin-wall cylindrical workpiece was analyzed by a numerical calculation method. When the three-jaw clamped thinwall cylindrical workpiece was considered as a parametric vibration system, the analytical results were consistent with the experimental results.
