Acoustic emission technique has the capability to provide efficient real-time knowledge and monitoring of the grinding process.Root mean square of grinding acoustic emission signal AERMS values are used to analyze the process characteristics.The acoustic emission measurement is employed for monitoring the temperature,force and studying the grindingmechanism of engineering ceramics.This paper explores the relations between the temperature,force,acoustic emission and surface roughness via the grinding of engineering ceramics.Some models for the relationship between the grinding acoustic emission signal of engineering ceramics partially stabilized zirconia and alumina and the grinding force,temperature and surface roughness areestablished.The acoustic emission monitoring in the grindingofengineering ceramics is perfected.It can be concluded that acoustic emission provides the clearest results and a common ground to predict the final surface quality and monitoring of process.
