Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl). When the voltage is applied across the two […]
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 (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 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

Today we will learn about what is carburetor – parts and its working. As we know spark ignition engines use volatile liquid fuels such as petrol for its working. Petrol is highly volatile and its ignition temperature is quite below the temperature that occurs in the engine cylinder before full compression. Hence, the mixing of air

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
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

In this article, we will discuss about the difference between SI engine and CI engine. The Spark Ignition (SI) engine, as its name indicates uses spark to ignite the fuel. In a Compression Ignition (CI) engine, the air is compressed within the cylinder and the heat of this compression air is used to ignite the

Since there are many types of springs but here I will discuss their types only on the basis of their shapes and how the load force is applied on them. The springs are defined as an elastic body which stores mechanical energy and gets distorted when loaded and regains its original shape when load is
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
