ABSTRACT OF THE DISCLOSURE The present invention relates to an integrated acoustic emission sensor for real time monitoring of manufacturing processes, utilizing a piezoelectric material sensor coupled directly to the machining tooling element that is desired to be monitored. Use of an inertial mass, as in conventional bulky acoustic emission sensors, is completely dispensed with. The sensor is suitably connected to sensing circuitry for providing an output signal as a function of acoustic emissions in such tooling element.
