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. These methods form a group of processes which removes excess material by various. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. 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 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.
