  • Process and device for monitoring the chip-removing treatment of a workpiece
    Patent number: 5159836
    Abstract: A process and device for monitoring the chip-removing treatment of a workce by analyzing the sound emission detectable on the tool which is transformed into an electrical signal, filtered, and compared with respect to its amplitude determined over a predetermined period of time with a predetermined adaptable threshold value. The constituents contained in the sound emission signal of the continuous basic noise signal resulting from the cutting and friction noise, and of the pulse-type chip-break signals superposed with respect to this with a higher amplitude, are separated and separately analyzed and evaluated.
