Study of Parameters of Ultrasonic Machining

Abstract

The recent development of modern hi-tech industries has given rise to the creation of a whole range of new materials. These include high strength, stainless and heat resistant steels and alloys, titanium, ceramics,composites, and other nonmetallic materials. These materials may not be suitable for traditional methods of machining due to the chipping or fracturing of the surface layer, or even the whole component, and results in a poor product quality. Similarly, the creation of new materials often highlights some problems unsolvable in a framework of traditional technologies. In certain cases these problems are caused by the construction of the object and the requirements particular to it. As an example, in microelectronics, its often necessary to connect some components without heating them or adding any intermediate layers. This forbids the use of traditional methods such as soldering or welding. Many of these and similar problems can be successfully solved using ultrasonic technologies. The USD (Ultrasonic Drilling Machine) uses a novel drive mechanism to transform the ultrasonic or vibrations of the tip of a horn into a sonic hammering of a drill bit through an intermediate free-flying mass.
