Abstract:   Advanced Ceramics are extensively i use in modern technological world. A major breakthrough is required in lowering the production costs and improving producibility and reliability in use for advanced-ceramic components and products to achieve their predicted potential. Machining is needed to produce the required size, shape and surface finishes not possible by forming methods. To accelerate to the researchers all over the world. This paper is an attempt to study the tool wear problems associated with machining methods like Diamond machining, Electrodischarge Machining, advanced ceramics etc. Experiments have been conducted to machine High Alumina, Silicon Carbide and Steatite using ultrasonic drilling process and the data thus generated has been analysed and inferences drawn. The paper also encompasses production accuracy, surface roughness, machining rates and tool wear value obtained while machining advanced ceramics.
