As a typical hard and brittle material,advanced ceramics are machined mainly by precision grinding and lapping of superhard fine abrasives.On-line monitoring of grinding process and timely adjustment of process parameters is an important way to ensure the surface quality of workpiece and improve grinding efficiency.Acoustic emission(AE)has been widely used in grinding process monitoring because of its high sensitivity and real-time response.This paper describes the basic principle of AE technology,summarizes the common signal analysis methods of AE monitoring in grinding process of advanced ceramics,as well as the research progress of AE technology in the fields of grinding wheel wear and dressing monitoring,grinding burn monitoring,workpiece surface quality prediction and intelligent grinding monitoring system construction at home and abroad.Combined with the current situation and shortcomings,the future application prospect of AE technology in grinding monitoring is prospected in order to promote the application expansion of AE technology in advanced ceramics grinding monitoring.
