Electron Beam Machining Book

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 eb machining is a powerful method for micro and nanofabrication because the beam can be focused to a diameter of the order of a few nanometers.

This process is used in many applications including drilling cutting annealing and welding.

Electron beam machining book. Electron beam machining ebm is a thermal machining process in which high velocity electrons concentrated into a narrow beam are used for instantly heating melting or vaporizing the material. Electron beam machining is a process in which high velocity electrons are concentrated into a narrow beam with a very high planar power density. Ebm can be used for very precise cutting or boring of a wide variety of metals. 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 machining ebm uses a focused beam of high velocity electrons to remove material. Electron beam melting ebm is an additive manufacturing technology which uses electron beam to melt metallic powder layer by layer and build fully dense parts. Electron beam machining free download as powerpoint presentation ppt pdf file pdf text file txt or view presentation slides online. Electron beam machining can be used to accurately cut or bore a wide variety of metals. A detailed notes on electron beam machining process and surely helps you. 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. This article provides a description of equipment used for ebm and discusses the process characteristics applications advantages and disadvantages of electron beam drilling. Yunitha ratnadilla tri adhi kusuma 11313560tk37951 electron beam machining a. 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. This property permits the fabrication of nanoscale patterns by using an eb sensitive polymer resist in a process called eb lithography ebl. The beam cross section is then focused and directed toward the work piece creating heat and vaporizing the material.
