Plasma arc machining process diagram application advantages and disadvantages.

What is plasma arc machining process. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. What is plasma arc machining. This channel is formed by faculty from bit to enhance the knowledge of students towards technical and fundamentals plasma arc machining is used for variety of industrial application. Parts working principle advantages application and more. The process employs two inert gases one forms the arc plasma and the second shields the arc plasma. The plasma arc welding and cutting process was invented by robert m. Gage in 1953 and patented in 1957. Plasma cutting achieves speeds greater than those of laser cutting systems for thickness over 3 mm. Advantages of plasmaarc machining rapid cutting speeds. The plasma arc process has always been seen as an alternative to the oxy fuel process. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. 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 cutting can be use for precision cutting on gauge material up to 6 thick stainless. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. 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.

That means we get the plasma state that we wanted for plasma arc machining. Filler metal may or may not be added. Plasma cutting can be combined with waterjet or oxy fuel on the same part. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. One thing to note down is that a high potential difference is applied in order to get the plasma state. Plasma arc cutting is faster than oxyfuel for cutting steel up to 50 mm thick and is competitive for greater thickness. Plasma cutting is the fastest cutting process on carbon steel aluminum or stainless steel. Plasma arc machining is a metal removal process in which the metal is removed by focusing a high velocity jet of high temperature 110000c to 300000c ionized gas on the workpiece. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. The term plasma as employed in physics means ionized particles.
