THIS PAPER ADDRESSES NEW TECHNOLOGIES FOR SENSING THE CONDITION OF THE GRINDING WHEEL AND FOR PROVIDING FEEDBACK ON THE EFFICIENCY OF THE GRINDING OPERATION FOR PROCESS CONTROL. A REVIEW OF SENSING CHALLENGES IN GRINDING IS PRESENTED. THIS PAPER DESCRIBES RECENT RESEARCH IN THE APPLICATION OF ACOUSTIC EMISSION SENSING TO GRINDING INCLUDING: SPARKOUT AND CONTACT DETECTION, WHEEL LOADING, WHEEL DRESSING, AND INFEED CONTROL FOR PLUNGE GRINDING. RESULTS OF EXPERIMENTAL EVALUATION OF THESE APPLICATIONS IS PRESENTED. THE RESULTS SHOW THAT THE ACOUSTIC EMISSION SIGNAL IS EXTREMELY SENSITIVE TO WHEEL/WORK CONTACT, WHEEL CONDITION AND METAL REMOVAL CHARACTERISTICS. SENSITIVITY TO WORK SURFACE BURNING IS ALSO DEMONSTRATED. THE MOST PROMISING APPLICATION OF THIS TECHNOLOGY SEEMS TO BE IN PRECISION GRINDING APPLICATIONS FOR WHICH CONVENTIONALLY MONITORED PARAMETERS (SUCH AS WHEEL CONTACT FORCES, LO
