Electron beam machining pdf. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. Due to pattern of electrostatic field produced by grid cup electrons are focused and made to flow in the form of a converging beam through anode. The cathode is generally made of tungsten or tantalum. Electron beam machining ebm the production of free electrons negatively charged particles are obtained by electron gun. 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. 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. 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. A detailed notes on electron beam machining process and surely helps you. Electron beam machining ebm electron beam machining is a thermal nontraditional process uses electrical energy to generate thermal energy for removing material. Working principle of electron beam machining. Electron beam machining is a thermal process used for the metal removal during the machining process. 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. Further the beam needs to be manoeuvred if required by the gun. Electron beam machining ebm advantages and disadvantages. In the electrical beam machining electrical energy is used to generate the electrons with high energy.

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 ebm uses a focused beam of high velocity electrons to remove material. It is mostly used to drill holes in any shape. Yunitha ratnadilla tri adhi kusuma 11313560tk37951 electron beam machining a. Electron beam machining free download as powerpoint presentation ppt pdf file pdf text file txt or view presentation slides online. This property permits the fabrication of nanoscale patterns by using an eb sensitive polymer resist in a process called eb lithography ebl. This article provides a description of equipment used for ebm and discusses the process characteristics applications advantages and disadvantages of electron beam drilling.
