Today plasma retains the original advantages.

Plasma arc machining iit. Understanding the basics of plasma arc cutting and plasma arc gouging will help welding operators be more successful with these techniques. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. That means we get the plasma state that we wanted for plasma arc machining. 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. The term plasma as employed in physics means ionized particles. Working principleelectron beam machining system electron beam gun power supply vacuum system and machiningchamberprocess parameterscharacteristics of. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. As the gas comes in contact with the plasma there is a collision between the atoms of a gas and electrons of an electric arc and as a result we get an ionised gas. Plasma cutting is used in cutting and gouging. A person doesnt need to be a physicist or chemist to understand the plasma arc. Later plasma arc has been sucessfully used for spraying surfacing welding metals like aluminium stainless steel titanium brass and copper though other conductive metals. The electric arc is formed between an electrode which is usually but not always made of sintered tungsten and the workpiecethe key difference from gtaw is that in paw by positioning the electrode within the body of the torch the plasma arc can be separated from the shielding gas envelope. Introduction plasma are initially employed to cut metals that are difficult to machine by conventional methods. The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw.

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 1. 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. Plasma arc machining. Plasma arc machining presented by rajkumar s w 1ms15mse10 mtech mse 25 apr 16 2. The topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques. Plasma arc machining pam plasma arc machining is a nontraditional thermal process.
