The purpose of this paper is to clarify the characteristics of cutting noise and noise sources in metal cutting with a single point cutting tool. When a cylindrical workpiece is machined with a lathe, the sound pressure level and frequency analyses were measured. Effects of overhang length of the cutting tool, cutting condition, tool wear, work material and shape of the workpiece on the cutting noise analyses were experimentally made clear. Two prominent peaks of the sound pressure level were observed from the frequency analyses of cutting noise at the frequencies of around 4000 Hz and 10 000 Hz. The former peak is caused by the vibration of the cutting tool system and the sound pressure level at the frequency increased with the increase of tool wear. The latter peak is affected by the workpiece system and the frequency of the peak varied with the decrease of wall thickness in pipe cutting with a lathe.
