THE STRUCTURE-BORNE SOUND EMITTED DURING THE GRINDING PROCESS (ACOUSTIC EMISSION, AE) IS ESPECIALLY SUITABLE FOR SUCH MONITORING. THE AE SIGNAL FROM THE GRINDING, DRESSING AND SHARPENING PROCESSES IS NOT SUBJECT TO TEMPERATURE DRIFT AND IS ULTRASENSITIVE UNDER PRECISION MACHINING CONDITIONS. AS AN INDIRECT PROCESS PARAMETER, THE AE SIGNAL IS CHARACTERIZED BY MUCH SHORTER RESPONSE TIMES AS COMPARED TO MACHINING FORCES OR MOTOR CURRENTS. THIS PAPER INDICATES SOME AE APPLICATIONS FOR TOOL LIFE MONITORING, DRESSING FAULT DIAGNOSIS AND SHARPENING PROCESS CONTROL.
