| 摘 要： | 介绍了回转球面精密磨削系统，在研究回转球面精密磨削原理和机床结构的基础上，分析了球体形状误差的产生原因，利用BP神经网络拟合进给量、磨削区段和砂轮主轴电流三者之间的非线性关系，通过网络预测调整不同磨削区段的进给量控制电流恒定从而达到恒功率磨削.

| Abstract: | A precision sphere grinding system was introduced.On the basis of mechanism of sphere grinding system and grinder structure,the cause of sphere form error was analyzed.BP neural network was used to fit the non-linear relationship between feed rate,grinding section and spindle current.And the current was kept stable by adjusting feed rate previously at different grinding section,therefore,constant power grinding was obtained. |

| Keywords: | neural network sphere grinding sphericity error |
