| Abstract: | Precision assignment of remanufactured parts is an important problem which is related to the performance of remanufactured machine tools and the cost of remanufacturing. The algorithm of BP and GA was presented to assign the precision parameters of remanufactured parts. A BP neural network model was constructed to represent the relationship between the precision parameters of parts and the volumetric error of remanufactured machine tools. The training sample data were obtained with orthogonal design and were used to train the network. The precision parameters of remanufactured parts were determined by the algorithm of BP and GA. The simulated results show that the algorithm is an effective approach to solve the complex problem of precision assignment. |
