摘要：

We are developing a new method using ultrasonic longitudinal and torsional vibrations of a hollow-type stepped horn with diagonal slits for hole machining. We foresee that, with this method, equipment can be simplified and miniaturized. In this study, ultrasonic vibration sources of a horn with diagonal slits and a uniform rod with diagonal slits are used. The longitudinal and torsional vibration characteristics of the horn are studied and the shape of the diagonal slits is examined. As a result, to obtain the maximum torsional vibration at the tip, the diagonal slit conditions were as follows: the center position of the diagonal slits was the position of the node of longitudinal vibration, the angle was 35 degrees, and the depth was 3.5 mm in all cases of cross-sectional ratio. It was clarified that a horn with diagonal slits can be used for hole machining of brittle materials. (C) 2011 The Japan Society of Applied Physics
