In Electron Beam Machining Workpiece Is Held In

Electron beam machining does not apply any cutting force on the workpiece thus very simple work holding is required. Ion beam machining ibm ion beam machining or etching is generally a surface finishing process in which the material removal takes place by sputtering of ions.

Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece.

In electron beam machining workpiece is held in. In an electron beam machining the electrons strike the. Electron beam machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. In this post you learn what is electron beam machining how its done with its working principle advantages of ebm accuracy and limitation of electron beam machining. Electron beam machining ebm ebm equipment equipment is contained in vacuum 10 4 mm hg or more in order to ensure cutting energy. Working principle of electron beam machining. This is why machining fragile and brittle materials is obtainable using this method. This will generate high heat energy and melts and vaporize metal from work piece. An electron gun is basically a triode consisting of. As electron beam machining is grouped under the thermal category it is natural to have thermal damages as part of the result. Electron beam machining ebm advantages and disadvantages. This whole process takes place in vacuum chamber. Electron beam machining ebm electron beam machining is a thermal nontraditional process uses electrical energy to generate thermal energy for removing material. In the electrical beam machining electrical energy is used to generate the electrons with high energy. Cathode to emit high negative potential electrons. Electron beam machining is the metal removal process by a high velocity focussed stream of electrons which heats melts and vaporizes the work material at the point of bombardment.

Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. The process is different from electric discharge electron beam laser and plasma arc machining in that the process does not depend on heating of the workpiece to the point of evaporation. When this high velocity electron strikes the workpiece it melts and vaporizes the material from the workpiece. It is mostly used to drill holes in any shape. Electron source is an electron gun several times the intensity of a tv gun. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. A pulsating stream of high speed electrons produced by a generator is focused by electrostatic and electromagnetic fields to concentrate energy on a very small area of work. 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. Electron beam machining is a thermal process used for the metal removal during the machining process.
