Ultrasonic Machining (USM) – Main Parts, Working Principle, Advantages and Disadvantages with Application

Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles. The motion of the tool takes place vertically or orthogonal to …

Laser Beam Machining – Main Parts, Principle, Working with Application

Laser Beam Machining (LBM) is a form of machining process in which laser beam is used for the machining of metallic and non-metallic materials. In this process, a laser beam of high energy is made to strike on the workpiece, the thermal energy of the laser gets transferred to the surface of the w/p (workpiece). …

What is Electrical Discharge Machining (EDM) Process and How it Works?

What is EDM (Electrical Discharge Machining)? Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In an EDM machine, the material is removed by …

What is Electron Beam Machining – Parts, Working, Advantages, Disadvantages with Application

Electron Beam Machining is a process in which high-velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. When this high-velocity electron strikes the workpiece, it melts and vaporizes the material from the workpiece. Working Principle of Electron Beam Machining In an electron beam machining, the electrons strike the …

What is Stress Concentration – Definition, Causes, effects and Prevention?

Stress concentration is the accumulation of stress in a body due to sudden change in its geometry. When there is a sudden change in the geometry of the body due to cracks, sharp corners, holes and decrease in the cross section area, then there is an increase in the localised stress near these cracks, sharp …

Difference Between Turbocharger and Supercharger

In this article, we will learn about the difference between turbocharger and supercharger. They both are forced induction system i.e. they compress the air from the atmosphere and sends it to the engine cylinder. The compressed air allows a double amount of fuel to enter into the cylinder for combustion. This doubles the power of …
