Plasma arc machining process pdf. 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. Introduction plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. In this process an inert gas is blown at high speed out of a nozzle. 56 ultrasonic machining 57 chemical machining processes 58 electrochemical machining 59 laser beam machining 510 plasma arc machining 511 summary 512 answers to saqs 51 introduction modern machining methods are also named as non conventional machining methods. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasmatypical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as wellplasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Plasma arc machining process diagram application advantages and disadvantages. The torch produces a high velocity jet of high temperature ionized gas called plasma that cuts by melting and removing material from the. The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. 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 plasma arc welding and cutting process was invented by robert m. A person doesnt need to be a physicist or chemist to understand the plasma arc. The process employs two inert gases one forms the arc plasma and the second shields the arc plasma.

Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. The plasma arc process has always been seen as an alternative to the oxy fuel process. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. Gage in 1953 and patented in 1957. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. The topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques. 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 term plasma as employed in physics means ionized particles.
