Abstract

Every product we use in day-to-day life has undergone the machining process either directly or indirectly. The importance of machining process can be judged from the fact that more than $100 billion is spent annually on machining related operations. Conventional machining processes stress the material beyond the yield point to start the material removal process. To achieve this purpose the cutting tool material should be harder than the workpiece material. With the discovery of new class of materials like nimonic alloys, alloys with alloying elements like Tungsten, Molybdenum and Columbium the conventional machining process are not suitable to put in use as machining these materials pose difficulty. Machining these materials with conventional methods is time consuming as well as difficult as the material removal rate decreases with increase in hardness. This led to development of non-conventional machining processes. Non-conventional machining processes do not replace the conventional machining process but supplement them. Some of the non-conventional machining processes are Electric Discharge Machining, Electro Chemical Machining, Electro Chemical Grinding, Ultrasonic Machining, Laser Beam Machining, Plasma Arc Machining, Water Jet Machining, Abrasive Water Jet Machining etc. With the development of non-conventional machining processes the production rate has been enhanced with increase in the product quality. Non-conventional machining processes had up to greater extent lowered the degree of further surface finishing requirement. In this paperwork literature has been studied in context to "Optimization of Process Parameters using Plasma Arc Machining". The work pieces of Stainless Steel were used for experiment purpose. The Taguchi Experimental Design was used for process optimization. The optimization values have been developed with the aid of Minitab-18 Software. Confirmation tests were done to check the genuineness of the values obtained through the software.
