The development of monitoring and control systems for ensuring process reliability in turning requires profound knowledge of the causal relations between process influences and effects. As cutting is a dynamic process, measured vibrations and acoustic emission are especially useful for process and system identification. The main dynamic excitation mechanism during turning is friction between tool and workpiece. Dependent on several parameters such as cutting velocity and normal loads, friction-induced vibrations occur in different kinds and intensities during turning. Furthermore, these vibrations are influenced by the wear-dependent contact conditions between tool and workpiece. Analysis of measured acoustic emission signals with methods of linear and non-linear dynamics has revealed transitions from moderate friction-induced vibrations to high-amplitude self-excited chatter for strongly worn tools.
