Design of The Tool Horn for Dies Needle Horning Manufacturing

Ultrasonic machining technology has been developed over recent years for manufacturing the quality-assured precision parts fur several industrial application such as optics, semiconductors, aerospace and automobile application. Ultrasonic needle horning is widely used in cutting(drilling) of non-conductive, brittle workpiece materials. This paper intends to understanding of the basic mechanism of ultrasonic needle horning. And frequency analysis program is used to easily predict the natural frequency of ultrasonic vibration cutting tools.
