Establishing Reliability Model of WEDM Based on Neural Network

At the beginning of Wire Electrical Discharge Machining(WEDM) reliability research,the mission reliability block diagram of system has not been established and the relationship between every sub-system has not been clearly,so a reliability modeling method based on neural network is proposed.The system reliability is taken as the output of the neural network,the reliability of every sub-system and the Mean Time between Failures(MTBF) are taken as the input of the neural network,and then the neural network is trained.The trained neural network has memorized the relationship between the system reliability,sub-system reliability and MTBF,so the reliability model of WEDM is determined.The example shows that the reliability model of WEDM based on the neural network has very strong estimation ability and high precision.
