Abstract

The application of human speech processing techniques to the machine shop may provide a new means to interpret the sounds created by the metal cutting process. Realtime signal processing in the frequency domain can identify those bandpass responses which indicate the health of the tools. When combined with knowledge of the tooling and the cutting path, spectrograms can verify the cutting phases and geometric features expected of a normal process.
