In order to guarantee the effectiveness of the CNC system and reach expected reliability level, reliability prediction model was established for the CNC system by BP neural network algorithm based on the particle swarm optimization. The weight and threshold value of BP neural network were optimized with the particle swarm optimization algorithm, the three-layer BP neural network prediction model was established, and practical failure data verification was conducted for the model established. Through the simulation verification, the result suggested that this scheme is accurate and effective. The improved algorithm improves the convergence rate and BP network learning ability, carries out successful prediction for the reliability of the CNC system, and provides basis for the design decision of the CNC system.
