The purposes of this study are to reduce the aerodynamic noise from a circular cutting tool. By making a slit longitudinally through the tooth, a circular cutting tool itself has effect on the aerodynamic noise reduction. A reason of the aerodynamic noise reduction is that the vortices generated behind a tooth are controled by a self-jet from a alit. The self-jet generated from a slit is much influenced by tooth spacing of a circular cutting tool. This paper presents the results of an investigation into the influence of the tooth spacing on the aerodynamic noise reduction using the slit tooth. The influence of the tooth spacing on the attenuation coefficient of sound pressure and St number is clarified from the experimental results.
