The Effects of Plasma Arc Cutting Process Parameters on Cutting Quality of Steel

During last thirty years there is a tremendous research in advance machining process? Now a day this advance non-conventional machining processes is the life line of any industry. One of the most important non-conventional machining methods is plasma arc machining. Its high accuracy, finishing, high speed and ability to machining any hard surface it become a very preferable for industry. According to available review it has been proved that by selecting proper process parameters we can cut any material by plasma arc machining with high MRR, lower kerf width, bevel angle and high surface finish. During last three or four years the investigation about parameters of plasma arc machining for mild steel, AISI 1017, SS304 and En 31 was already done. In this review paper the various process parameters of plasma arc cutting machine and their influence on the cutting quality of steel is to be studied. For this study the current, standoff distance, cutting speed and gas pressure are referred as process parameters. And surface roughness and material removal rate was selected as response parameters.
