【Abstract】 On line monitoring for grinding arc temperature is a necessary and important section to realize automation of grinding process. This paper introduces an on line monitoring system based on artificial neural network. The structure of on line monitoring system,the method of temperature measurement and the detailed monitoring process are also presented. In order to monitor and forecast grinding arc temperature dynamically, an improved BP network is designed as a temperature forecasting model. It is proved by technological experiments that the monitoring system can better realize on line monitoring and forecasting for grinding arc temperature.更多还原
