This whole process takes place in vacuum chamber. Electron beam machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. The source of energy in electron beam machining is high velocity electrons. To machine a piece of Glass using Electron Beam Machining, the penetration depth is affected by: A) The speed of electrons used B) The number of lenses used C) The thickness of the workpiece D) All of the above E) None of the above The whole process takes place in vacuum. Electron Beam Machining is a non-conventional machining process or Non-traditional process. In an electron beam machining, the electrons strike the workpiece with a high velocity. Electron beam exposure is a processing method that uses the effects of electron beam radiation (see Electron beam power density up to At W / cm2, the material where the electron beam strikes is locally melted; when the electron beam moves relative to the workpiece, the molten metal is continuously solidified. Electron beam machining (EBM) uses a focused beam of high-velocity electrons to remove material. As the electron strikes the workpiece, the kinetic energy of the electron changes into heat energy. Electron beam machining is same as laser beam machining process in which except laser, high speed electron beam impinges on work piece. Workpiece is mounted on a CNC table so that holes of any shape can be machined using the CNC control and beam deflection in-built in the gun. The heat energy so produced is used to melt and vaporize the materials from the w/p. It is mostly used to drill holes in any shape. When high-speed electrons in a densely focused beam impact with the workpiece surface, most of the kinetic energy of the electrons is converted into heat energy. In an electron beam machining the electrons strike the. This phenomenon has been well understood since the development of electron microscopy when attempts to use the electron beam as a machining … Electron Beam Machining (EBM) is a machining process in which material is removed from the workpiece by focusing a beam of high-velocity electrons towards the workpiece. In electron beam machining workpiece is held in. EBW is often performed under vacuum conditions to prevent dissipation of the electron beam. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. Electron beam guns are also provided with illumination facility and a telescope for alignment of the beam with the workpiece. A typical triode EBM gun functions in a manner very similar to an EBW gun. This will generate high heat energy and melts and vaporize metal from work piece. Electron Beam Machining can machine metallic as well as nonmetallic workpiece. This article provides a description of equipment used for EBM and discusses the process characteristics, applications, advantages, and disadvantages of electron beam drilling. The appearance of EBM equipment is very similar to electron beam welding equipment. 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.
