The topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques.

Plasma arc machining process in pdf. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. A person doesnt need to be a physicist or chemist to understand the plasma arc. The torch produces a high velocity jet of high temperature ionized gas called plasma that cuts by melting and removing material from the. The plasma arc welding and cutting process was invented by robert m. Introduction plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. The plasma arc process has always been seen as an alternative to the oxy fuel process. 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. Plasma arc machining pam plasma arc machining pam is a material removal process in which the material is removed by directing a high velocity jet of high temperature 1100030000c ionized gas on ecause of the high temperature involved the process can be used on almost all materials including those which are resistant to oxy fuel gas cutting. Plasma arc machining process diagram application advantages and disadvantages. Today plasma retains the original advantages. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. 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 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. In this process an inert gas is blown at high speed out of a nozzle.

The plasma arc cutting process is illustrated in fig. The process employs two inert gases one forms the arc plasma and the second shields the arc plasma. Filler metal may or may not be added. The term plasma as employed in physics means ionized particles. 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. 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. Plasma arc machining pam plasma arc machining is a nontraditional thermal process.
