Abstract

Advanced ceramics such as aluminium oxide, silicon nitride are on the attractive side for various applications due to their valuable properties but the reason for their limited use in the market is their high cost of machining through the conventional process like ultrasonic machining, so to reduce their machining cost and make them valuable and competitive in market there is need for the development of machining process which not only reduces the machining cost but also able to achieve high Material Removal Rate. One such process for that is Rotary Ultrasonic Machining (RUM) which is a combination of Ultrasonic Machining and Diamond Grinding. This paper reviews the effect of various process variables on Material Removal Rate, Tool Wear, Surface and Sub-surface Cracks of ceramic component with Rotary Ultrasonic Machining and compares them with the conventional Ultrasonic Machining.
