| Summary: | In order to analyze the nonlinear dynamic behavior of the milling chatter，firstly to analyze the
varying depths of cut during milling stationary vibration signal the vibration signal and bred flutter vibration signal
nonlinear characteristics based on the phase difference and the maximum Lyapunov exponent permutation entropy
ect of the vibration signal of the workpiece. Then to develop the milling vibration signal acquisition and analysis
system for online forecasting milling chatter experiment based on virtual instrument platform. The experimental
results showed that，the phase of vibration signal characteristics can effectively detect the milling chatter. But that
can＇t be effective prediction of cutting chatter. At the different stages of cutting chatter，the sensitivity of the
Lyapunov exponent of the vibration signal is different. The threshold of permutation entropy is also different. The
characteristics of phase difference and chaotic characteristics can be used as an effective method for the
identification of chatter. |
