Abstract: The Kirchhoff’s vibration theory of cantilevered thin-walled beam is applied to the milling of thin-walled components and is considered to agree with the principle of small deflection vibration. Based on the milling tests, the chatter model of end milling of thin-walled components is built and the differential equation of chatter is derived also. The chatter model is simulated according to the practical cutting conditions. The measured results are in good agreement with the simulating results. The feasibility of this assumption is demonstrated. The results can be used in analyzing and milling of the correlated thin-walled components. All these work lays a reliable founda-tion to the further studies on the chatter rules of thin-walled components.
