Generally, a diamond circular saw blade generates the vibration and the noise when it is rotating at high speed. Under the specific condition, the noise called "whistling noise" which has sound pressure level of over 110 dB occurs. This whistling noise causes working environmental pollution. In this paper, the effects of the number of segments, the slits, and the natural vibration of the blade on the generation of whistling noise were investigated experimentally. The main results obtained are as follows : (1) The generation of whistling noise is influenced by the rotational speed of the blade. (2) The rotational speed generating the whistling noise increases with an increase of number of segments. (3) The generation of the whistling noise is concerned with the natural vibration and the peripheral air flow of the blade due to the slits.
