【Abstract】 Taking GCr15 laser surface quenching for example, the authors apply the neural network technology based on genetic evolution(GANN) to laser quenching field, build the prediction model of laser quenching performance, decide the function reflection relation between the technological parameters and performance indexes of laser quenching and realize the prediction of laser quenching performance. The experiment results show that the errors between the prediction value and the practical measure are less than 7%, proving the reliability of the performance prediction model.更多还原
