Abstract: Self-excited oscillation in turning process is a kind of unstable phenomenon resulting from former vibration trace. Eliminating of the phenomenon is a key technology in cutting process. Back propagation neural network (BP network) is introduced to control behaviors of nonlinear or unstable system. According to neural network control technology a new technology for the elimination of self-excited oscillation in turning process is put forward. Numerical simulation examples show that such technology plays special roles in the eliminating of self-excited oscillation and the control of turning stability.

Key words: Neural network, Regenerative chatter, Self-excited oscillation
