The principle of working of the sliding head type single spindle automatic machine is explained by the sectional view of old type of machine as shown in Fig. 34.2. However some refinements have been carried out in it, but the working principle remains the same.
Laser Beam Machining (LBM) Working Principle. In laser welding (LBM) the joint is made either as a sequence of overlapped spot welds or as a continuous weld. Laser welding is used in the electronics, communications and aerospace industries, for the manufacture of medical and scientific equipment, joining small components.
Laser is an acronym for light amplification by stimulated emission of radiation. Laser Beam Welding (LBW) is a fusion joining process that produces coalescence of materials with the heat obtained from a concentrated beam of coherent, monochromatic light impinging on the joint to be welded.
The underline working principle of laser was first put forward by Albert Einstein in 1917 though the first industrial laser for experimentation was developed around 1960s. Laser beam can very easily be focused using optical lenses as their wavelength ranges from half micron to around 70 microns.
ADVERTISEMENTS: The principle of working of the sliding head type single spindle automatic machine is explained by the sectional view of old type of machine as shown in Fig. 34.2. However some refinements have been carried out in it, but the working principle remains the same. This machine has been developed for manufacturing quantities of […]
Mar 27, 2017· Today we will learn about ultrasonic welding principle, working, equipment's application, advantages and disadvantages with its diagram. Ultrasonic welding is a welding process in which ultrasonic waves or vibrations are used to generate heat for welding. Ultrasonic means those vibration waves which have frequency above the normal hearing range.

Apr 21, 2015· LBM is nontraditional thermal process. In thermal removing processes, thermal energy, provided by a heat source, melts or vaporizes the volume of the material to be removed. Among thermal removal methods, Electrical discharge machining or EDM is the oldest and most widely used. Electron-beam (EBM) and laser beam machining (LBM) are newer ...
Working Principle of Plasma Arc Machining The principle of plasma arc machining is shown in the figure. In a plasma torch, known as the gun or plasmatron, a volume of gas such as H2, N2, 02, etc. is passed through a small chamber in which a high-frequency spark (arc) is maintained between the tungsten electrode (cathode) and the copper nozzle ...

Fig. 15-3 shows the sketch of gas turbine of constant volume type. The air drawn from the atmosphere is compressed in the compressor to a pressure of 15 N/cm 2 to 35 N/cm 2 and forced into the combustion chamber through the valves. The oil which is stored in the fuel tank is pumped into the combustion chamber through the injector by means of a fuel injection pump.
Electric discharge machining, also known as spark erosion, electro-erosion or spark machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool cathode and the work anode. Fundamentally, the electric erosion effect is understood by the breakdown of electrode material accompanying any form of electric ...
Selective laser melting (SLM), also known as direct metal laser melting (DMLM) or laser powder bed fusion (LPBF), is a rapid prototyping, 3D , or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together. To many, SLM is considered to be a subcategory of selective laser sintering (). ...

Working Principle of Laser Beam Machining. The principle of a laser can be explained as follows: Let us consider that the atoms of a medium (for example, a ruby crystal rod) are at the ground state. When a quantum of energy from a light source is made to fall on this medium, it causes absorption of radiation by the atoms of the medium.
Apr 08, 2017· Working Principle. In an electron beam machining, the electrons strike the workpiece with a high velocity. As the electron strikes the workpiece, the kinetic energy of the electron changes into heat energy. The heat energy so produced is used to melt and vaporize the materials from the w/p. The whole process takes place in vacuum.
