In recent years, there are various ways of determining the cutting conditions. In this study, we focused on the cutting sound. Peripheral turning of carbon steel (C0.45%) by using a lathe were carried out in order to examine relationship between tool wear and waveform. Characteristic signals were extracted by FFT analysis of the waveform. As a result, it was found that the sound pressure of a specific frequency range is increased during cutting process. Moreover, sound pressure rise factor on the hypothesis; (1) frictional sound of the tool flank (2) frictional sound of the tool rake face (3) Sound from the shear deformation. We considered the generation mechanism of cutting sound.
