Abstract: This paper investigates the selection method of vari-speed milling parameters by experiments. The orthogonal experiments of vari-speed milling were studied on a given speed according to the stability lobes, and various parameters were selected. The experimental results show that varying speed milling approach possesses effects on vibration suppression on proper parameters selection though the acceleration damping ratio γa and the sound damping ratio γs. The variance analysis of dual factors test is adopted to data process and the acceleration damping ratio γa is taken as the evaluation index of vibration suppression. Finally, the preliminary conclusions on how to select proper parameters are obtained on the basis of the analysis of the experimental results, which is applied to online monitoring techniques using vibration to achieve automatic control of variable speed cutting.

Abstract: The axial limit cutting depth(LCD) of constant speed were studied, and the stability lobes were gotten by expriments and simulation. The vari-speed milling selected various parameters was investigated by expriments,also.The experimental results show that varying speed milling approach improves the limit cutting depth on proper time and prope parameters selection. According to the comparative analysis of the exprimental results of constant speed and vari-speed milling, it was obtained whether the varying speed milling approach was to be chosen and how to select proper parameters, should be reference to the stability lobes of constant speed.
