Abstract:
To predict the stability of the thin-walled components milling,the dynamic characteristics of the spindle-tool set and the workpiece are analysed respectively by the finite element modal analysis method and the experimental modal analysis method.The flexible workpiece vibration modes are available for partitioning the distinct machining stages that denote the dynamic variation characteristics of the workpiece in the process and for selecting the high-order dynamic frequency modes that can produce the displacement at the tool-cutting position as the virtual vibration modes to predict the cutting stability.For the thin-walled components milling,a system structural transfer function is proposed,which consists of a sub-section that describes the interaction of the spindle-tool set model and the workpiece dynamics,considers the machining stages position,and depends on the virtual vibration modes.The stability prediction results are in good agreement of the experimental results.The high precision of the system transfer function is proved.
