DEVELOPMENT AND EXPERIMENTAL STUDY OF PROCESS PARAMETERS IN ULTRASONIC TURNING

Abstract

Now-a-days. applications of many intractable materials such as ceramics, glass. tungsten, nickel and titanium based alloys have been gradually increasing. Machining of these materials with conventional, for example turning, is very difficult. In order to overcome this difficulty. a new advanced machining process has been developed, which is proposed to be known as Ultrasonic Turning (UST). Ultrasonic Turning is a non-traditional advanced manufacturing technique targeted for machining hard and brittle materials. Unlike many other advanced manufacturing processes such as electrochemical machining (ECM), electric discharge machining (EI)M). laser beam machining (LBM) etc., ultrasonic turning does not cause any measurable thermal damage to the workpiece. In the present work, an experimental setup was developed for implementing the proposed ultrasonic turning process and turning was performed successfully on borosilicate glass. Subsequently, the concept was future extended to perform threading on the same glass material. Preliminary investigations confirm that turning and threading on a borosilicate glass 4' could be successfully achieved using ultrasonic turning process.
