Plasma Arc Machining Nptel Notes

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 plasma arc machining is a nontraditional thermal process.

Plasma Arc Machining

Technical Note

Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch.

Plasma arc machining nptel notes. 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 term plasma as employed in physics means ionized particles. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. 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. 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. 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. The topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques. These methods form a group of processes which removes excess material by various. The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr. Today plasma retains the original advantages. A person doesnt need to be a physicist or chemist to understand the plasma arc. In this process the material is removed with the help of a high velocity travelling at half the speed of light ie. 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 process diagram application advantages and disadvantages.
