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:
