Abstract:

By three-dimensional milling simulations of Aviation Aluminum 7050-T7451 with metal cutting finite element analysis software AdvantEdge FEM, milling force data was obtained and amplitude-frequency characteristics was achieved through Fourier transformation of milling forces. According to mathematical statistical analysis of milling force data, we illustrates that the high-speed milling is a multi-blade interrupted cutting process and the tool vibration is a random vibration. Correlation functions and power spectral density functions of milling force and displacement were calculated in terms of signal processing discipline.
