英文摘要：

In this paper, according to the characteristics of acoustic emission on high sensitivity and fast response speed, firstly, the basic principle, development and characteristics of acoustic emission and signal analysis method were in- troduced. Secondly, the application of the acoustic emission technology to the monitoring of grinding process, surface quali- ties and intelligent grinding were presented. Finally, the current situation, problems existed and the tendency of acoustic emission monitoring grinding system were discussed.
