Abstract

The Electric Discharge machine (EDM) has evolved from a non traditional machining process and positioned itself in industries as a most indispensable conventional machine. It is multipurpose and excels with ability of precisely producing difficult-to-machine, geometrically complex component of any hardness. Low material removal rate (MRR) restricts its productivity. Abrasive Jet Machine (AJM), another versatile process acquires edge of quick set up and rapid machining of virtually any material. Key advantage is that it do not cause any heat affected zone; is flexible and able to machine hard and brittle materials. The major limiting factor is that the process produces a tapered cut. Hybridization is an approach to tackle more than one process in order to add their advantages and avoid the limitations. This paper proposes an indigenously developed hybrid system to take advantage of the best part of each of the above processes. The appropriate abrasives are routed along with compressed air through the hollow electrode to construct the hybrid process of AJM and EDM i.e. Abrasive Assisted Electric Discharge Machining (AAEDM). An attempt is made to study the benefits of the hybrid process over the standard EDM and results are verified by confirmation experimentation. The main process parameters were varied to explore their effects on material removal rate and surface integrities. The experimental results show that the hybrid process of AAEDM can enhance the machining efficiency and the developed hybrid process can fit the requirements of modern manufacturing challenges.
