【Abstract】 Acoustic emission technology have been attended broadly on mechanical processing recent decade,its theory and method have become as an important research field for modern manufacturing system used to monitor the processing state.This paper states the base principle of acoustic emission technology,discusses the fountain of acoustic emission,pro ducing mechanism and spreading disciplinarian in grinding processing.Re searching development of acoustic emission tech nology on grinding processing monitor is introduced,and some main prob lems and developing direction are pointed out in this paper.更多还原
