Abstract

The invention relates to a method for the automatic supervision of mechanical workings, based on the acoustic emission (AE), characterised in that the signal to be used for the automatic supervision is obtained by the subtraction of two different AE signals, acquired by two sensors, the first sensor substantially revealing the acoustic signal, generated by the workpiece and juxtaposed to the electromagnetic disturbance signal, the second sensor substantially revealing the only disturbance signal, the resulting signal being transmitted to a processing and control system. The invention also relates to a device for the automatic supervision of mechanical workings, based on the acoustic emission (AE) due to the working of a metallic piece (5) by the tool (6), characterised in that it comprises two sensors or transducers (1) or (1a), a unit (8) for the preliminary processing, substraction of said signals and ether transmission of the signal obtained, a receiving unit (9) and control (18, 19)
