【Abstract】 Based on the experiment of cutting force coefficient identification,the mathematical model of cutting force was established.The formula and the curve of the "一" shaped thin-wall part amplitude responses were obtained by combining finite element dynamic analysis with milling vibration mathematical model and extended to the complex thin-wall parts of aviation.According to the relationship of rotate speed and frequency of the workpiece,the program of parameterized dynamical characteristic analysis was programed to realize optimization of the milling parameters of thin-wall part.更多还原
