Abstract: An objective of this study is to develop a new method for the prediction and the avoidance of chatter vibration in milling operation of thin-walled structure by using 3D-CAD and CAE approach. Also, a new identification method for the modal parameters of a vibration system by analyzing radiated sound pressure from vibrated workpiece accelerated by an impulse force is proposed. Then chatter stability lobes are predicted using those modal parameters. Stiffness and modal shapes of the workpiece were obtained using…
