Aerodynamic noise caused by a circular cutting tool is reduced by adopting special tooth shape. This tooth is machined a longitudinal slit throuh the face of the tooth for the purpose of ventilation. A reason of the aerodynamic noise reduction is that a vortices generated behind a tooth are controled by a self-jet from a slit of the real slit tooth. From the experimental results, it is possible to reduce the aerodynamic noise sufficiently by using the real slit tooth. This paper presents the results of an investigation into the influence of the slit width and tooth spacing on the noise reduction. Furthermore, the influence of the slit tooth to the St number on the aerodynamic noise is clarified from the experimental results.
