ABSTRACT:
An apparatus and a method are provided for checking a machining process of a machine tool, for example a grinding machine, to obtain information about the quantity of a material removed and the wear condition of a grinding-wheel. The apparatus comprises an acoustic sensor adapted to detect acoustic signals generated by contact between the grinding-wheel and the piece being machined, and a force-detecting sensor adapted to detect the force applied between the grinding-wheel and the piece during the machining. The method comprises processing signals provided by both sensors, defining time intervals on the basis of the signals of the acoustic sensor, and monitoring the signals of the force-detecting sensor in the time intervals.
