Abstract

As chatter occurs suddenly, its control is difficult -- workpiece damage may occur before corrective action can be taken. Modeling the onset of chatter will lead to the prediction of chatter in advance of its occurrence and so will increase the time available for the system response. In this research work, a chatter model for turning is developed which explicitly includes the effect of changing tool position along the longitudinal direction of the workpiece during cutting and the realistic boundary conditions of the workpiece. Linear stability analysis is used to determine the conditions at the onset of chatter. To be useful in real time application, a novel chatter onset prediction algorithm is developed based on the chatter model.
