Abstract
Elliptical Vibration Cutting is a better-performance method compared with Conventional Vibration Cutting. Therefore I have developed newly typed elliptical transducer which is practical use under bearable condition. This is new technology to generate elliptical vibration which is compulsory accorded with longitudinal vibration's resonant frequency in real time. As amplitude of vibration for the point of tool is in enough width, it can be generated elliptical vibration in stability for hours. The result of cutting test : We have confirmed that Elliptical Vibration Cutting has its superiority compared with Conventional Vibration Cutting. Furthermore we are sure that it is for practical us in sufficiency.
