Plasma Arc Machining Parameters

Plasma arc machining pam plasma arc machining is a nontraditional thermal process. Plasma arc cutting pac is a widely used industrial process for the cutting of different types of metals in several operating conditions.

Process Parameter Analysis Of Plasma Arc Cutting For Surface

Plasma Arc Machining Process

Plasma cutting achieves speeds greater than those of laser cutting systems for thickness over 3 mm.

Plasma arc machining parameters. The plasma arc process has always been seen as an alternative to the oxy fuel process. Today plasma retains the original advantages. That means we get the plasma state that we wanted for plasma arc machining. For this experiment we have chosen stainless steel 316l ss316 l material. The term plasma as employed in physics means ionized particles. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. Cv kurnia abadi cnc plasma cutting engaged in cnc plasma cutting based metal cutting services the manufacture of ornaments from steel metal to aluminum. Oxy fuel and laser cutting in particular for cutting of mild. The topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques. The appropriate orthogonal array has been selected regarding number of factors available in that industry and the experimentation was carried out. Study of process parameters in plasma arc machining process. A person doesnt need to be a physicist or chemist to understand the plasma arc. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. Optimization of process parameters and quality results using plasma arc cutting in aluminum alloy plasma cutting is a thermal cutting using a plasma arc that is widely used in metal cutting. In our work we are going to optimize the machining process parameters of plasma arc machining.

Plasma arc cutting is faster than oxyfuel for cutting steel up to 50 mm thick and is competitive for greater thickness. 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. Pac is considered a challenging technology compared to its main competitors. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. 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. Advantages of plasmaarc machining rapid cutting speeds. The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr. 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. 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 plasma arc cutting process is illustrated in fig. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path.
