As a series of the sonic technique application, especially relating to clock's buzzer, we have been planning the development of an ultrasonic saw for the electric material cutting. As regards the cutting of electric material, aluminum, glass epoxy and iron plates for example, by handy ultrasonic saw, the objectives of the present study are, (1) to investigate the effectiveness of the ultrasonic saw, and (2) to compare the surface condition cut by the ultrasonic saw with that by the hack and jig saw brade. Acoustic power tested here is 10W. As a result, it is proved that the cutting speed is several times higher than that by the hack and jig saw, however, the surface is much more rough as compared with that by the hack and jig saw. Although a loading by a plastic flow effect was observed in the hack and jig saw, it was not observed in case of the ultrasonic saw.
