The machining process in which a water jet is used to remove material from the workpiece is called Water jet machining(WJM).In this process, a water jet is used which acts as a tool in the form of water saw.In this process water is greatly accelerated and further concentrated on the target workpiece.This water jet at…
Electrochemical machining is a non-traditional machining process. In the electrochemical machining process, a combination of electrical energy and chemical energy is used to remove material from the workpiece.This process is characterized as a reverse electroplating process but this process removes material instead of depositing it. This process is a non-contact process in which the cavity…
Babcock and Wilcox Boiler is a horizontal, externally fired, water tube, natural circulation boiler.This boiler is named after the persons who discovered it. It was discovered by Herman Babcock and Stephen Wilcox in 1967.This boiler is called natural circulation boiler because the circulation of water in the boiler is maintained by convective current.This boiler is…
Atomic Hydrogen Welding ( AHW ) thermo-chemical is a welding process in which welding is done using the arc produced between two tungsten electrodes and hydrogen gas provided by a hydrogen gas cylinder.It is named atomic hydrogen welding because the arc disassociates the hydrogen into atomic form. This process is also known as atomic arc…
A turret lathe is a semi-automatic lathe machine that is used for repetitive production of lathe parts.It is advance from the lathe machine produced earlier as it has a hexagonal turret.Hexagonal turret is an indexable tool holder which can hold six tools at a time. With the help of hexagonal turret, multiple cutting operations can…
Pirani Gauge is a device that is used to measure pressure, especially in vacuum systems. It was invented by a German physicist Marcello Stefano Pirani in the year 1906.It is based on a hot metal wire suspended in a tube and exposed to gas pressure media. This hot metal wire is made up of thin Tungsten, Nickel,…
Bevel protractor is an instrument that has a graduated circular scale with one pivoted arm that is used for measuring or making off the angles.This instrument is capable of measuring angles with a least count of 5′ or 5 minutes.It is used to measure the angle of any workpiece. It is used for various objects like jigs.Sometimes the…
Pelton turbine is an impulse turbine named after an American engineer Lester A.Pelton.Pelton turbines are suitable for power extraction when water energy is available at a high head and low flow rate.In this type of turbine, the potential and the pressure energy of water is converted to kinetic energy. A nozzle is used which increases…
Ultrasonic Machining Process is a non-conventional machining process used for machining both conducting and non-conducting materials. This machining process can be used to machine such materials that cannot be machined by the conventional machining process. Ultrasonic Machining is mainly used in brittle materials.As the name suggests, the machining process makes use of ultrasonic vibrations in…
Chemical Machining is the process of removal of material from the workpiece using chemical reactions by immersing the workpiece into a chemical solution.Chemical Machining is a process used for metal removal purpose by dissolution in a controlled manner from the workpiece by the application of acidic or alkaline solution and this solution is called etchant.The chemical…
