| Abstract: | The purpose of tolerance design is to find the best combination of the individual component tolerances in the given assembly under the condition that the assembly requirements are satisfied so that the production cost is minimum. Based on neural networks and genetic algorithm, this paper presents a new reverse approach for the tolerance design considering machine capabilities and mean shifts, which can present the real condition of the component production. A mathematical model has been given, and it is realized by using neural network and genetic algorithm. At last, an example is given and the results are analyzed. |
