Laser Beam Machining Main Parts Principle Working With
Therefore the heat generated is sufficient to melt and join the workpiece called an electron beam welding operation.
Electron beam machining diagram. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on. Laser beam machining is a non conventional machining method in which the operation performed by the laser. When this high velocity electron strikes the workpiece it melts and vaporizes the material from the workpiece. Electron beam machining ebm advantages and disadvantages. The working principle of laser beam. Laser beam machining working principle. As the electrons strike the work piece with high velocity their kinetic energy is transformed into thermal energy which melts and vaporizes the material. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. Today we will learn about electron beam machining principle working equipments application advantages and disadvantages with its diagram. The laser stand for light stimulated emission of radiation. Electron beam machining ebm is a process where high velocity electrons concentrated into a narrow beam are directed toward the work piece creating heat and vaporizing the material. Electron beam machining is a thermal process used for the metal removal during the machining process. Electron beam welding is a liquid state welding process. Working principle of electron beam machining. It is a non traditional machining process in which no physical tool is used.
The process used thermal energy to remove material from a metallic surface. The deflecting coils allow the beam to have a range of movement of 12 mm. In electron beam machining if the voltage given to the electron gun is about 60 to 70000 volts the velocity of electrons produced is reducing heat generation at the workpiece is reducing. Electron beam machining ebm is a metal removal process by a high velocity focused stream of electrons. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Electron beam welding ebw is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined. The electron beam can be controlled very accurately and machining tolerances of 0005 mm are possible. Electron beam machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. Today we will learn about electron beam welding principle working equipments application advantages and disadvantages with its diagram. Ebm can be used for very precise cutting or boring of a wide variety of metals. An optical viewing system is required in order to allow the operator to see the work in order to position the beam. In the electrical beam machining electrical energy is used to generate the electrons with high energy.
