Abstract
In this study, a practical inclined ultrasonic-vibration cutting tool, on which commercially available indexable inserts of various shapes can be mounted, is investigated. Such a tool can be achieved by using it in the longitudinal-vibration mode and optimizing the shape of the tool shank. Some cutting tools for turning operations, such as cylindrical turning and facing, are fabricated, and turning tests using the fabricated tools on a NC-lathe are carried out. Consequently, it is found that the fabricated inclined ultrasonic-vibration cutting tool is as useful as a conventional cutting tool, and a high accuracy can be obtained when it is used for cutting such as facing, turning for a cone and threading which are all difficult to achieve under a high cutting speed condition.
