The plasma arc process has always been seen as an alternative to the oxy fuel process.

Plasma arc machining process parameters. One of the most important non conventional machining methods is plasma arc machining. The term plasma as employed in physics means ionized particles. In this part of the series the process fundamentals are described with emphasis being placed on the operating features and the advantages of the many process variants. The plasma arc welding and cutting process was invented by robert m. The process employs two inert gases one forms the arc plasma and the second shields the arc plasma. Optimization of process parameters and quality results using plasma arc cutting in aluminum alloy plasma cutting is a thermal cutting using a plasma arc that is widely used in metal cutting. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. In this process an inert gas is blown at high speed out of a nozzle. Cv kurnia abadi cnc plasma cutting engaged in cnc plasma cutting based metal cutting services the manufacture of ornaments from steel metal to aluminum. Working principle plasma arc cutting is a very complex process that is used in order to cut steel and other metalsor sometimes other materials using a plasma torch. Today plasma retains the original advantages. In last forty years there is tremendous research in machining and development in technology. Its high accuracy finishing ability of machining any hard materials. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. Gage in 1953 and patented in 1957.

Introduction the plasma arc machining process was introduced to the industries in 1964 as a method of bringing better control to the arc welding process in lower current ranges. The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr. Filler metal may or may not be added. A person doesnt need to be a physicist or chemist to understand the plasma arc. The topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques. With increase in competition in market and to attain high accuracy now a days the nonconventional machining are become lifeline of any industry. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Kumar tapan kr barman prasna sahoooptimization of process parameters in plasma arc cutting of en 31 steel based on mrr and multiple roughness characteristics using grey relational analysis. The plasma arc cutting process is illustrated in fig.
