Plasma Arc Machining Theory

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 plasma arc formation begins when a gas such as oxygen nitrogen argon or even shop air is forced through a small nozzle orifice inside the torch.

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

Plasma arc machining theory. 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. However as with any piece of equipment you need to know how and why it does what it does and the necessary precautions to do the job safely. The term plasma as employed in physics means ionized particles. Unconventional machining processes plasma arc machining how plasma arc machining takes place high temperature machining. 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. Leco content we use cookies to help our website work more effectively and efficiently and to align our services and advertisements to your needs. Today plasma retains the original advantages. 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. 100 plasma arc cutting process plasma arc cutting is such a simple process you could almost take it out of the box and start using it. A person doesnt need to be a physicist or chemist to understand the plasma arc. Cutting process and theory include the fundamentals of plasma cutting. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material resulting in a cleaner faster cutting process than with oxyfuel. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw.

The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr. 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.
