Electron Beam Machining Introduction

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 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.

Electron Beam Melting Ebm Process Additive Manufacturing

This will generate high heat energy and melts and vaporize metal from work piece.

Electron beam machining introduction. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. The report aims at estimating the market size and future growth of the electron beam machining industry based on offering process application vertical and region. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. Ebm can be used for very precise cutting or boring of a wide variety of metals. Introduction electron beam machining is one of the examples of non conventional machining under the thermal process category along with laser beam machining electric discharge machining and plasma cutting. The research situation of the previous various electron beam machining methods and applications was discussed and the various. This whole process takes place in vacuum chamber. Educators introduction prakhar shrivastava i am an industrial and production engineering graduate jec jabalpur gate 2016 air 03 pi gate score 9391000 cracked written and interview for ieor iit b currently pursuing pgdie from nitie mumbai one of the 15 centers of excellence including iits. Electron beam machining market size research report identifies new revenue opportunity in electron beam machining. Introduction ebm electron beam machining ebm is a thermal material removal process that utilizes a focused beam of high velocity electrons to perform high speed drilling and cutting. The cathode is generally made of tungsten or tantalum. 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 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. It is mostly used to drill holes in any shape. Yunitha ratnadilla tri adhi kusuma 11313560tk37951 electron beam machining a.

Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Through introduction of the principle and characteristics of electron beam machining technology the application status and application instance of electron beam in research of materials science and materials processing in recent years were introduced in detail. Used with high power density to machine materials. Electron beam machining equipment the basic functions of any electron beam gun are to generate free electrons at the cathode accelerate them to a sufficiently high velocity and to focus them over a small spot size. Unconventional non traditional machining electron beam machining part b prakhar shrivastava. Further the beam needs to be manoeuvred if required by the gun.
