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. Electron beam micromachining it is a type of thermal micromachining processes. 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. An electron beam 3. Electron beam machining definition electron beam machining ebm is a process where high velocity electrons concentrated into a narrow beam are directed toward the work piece surface to remove material by melting vaporization. Today we will learn about electron beam machining principle working equipments application advantages and disadvantages with its diagram. Here we discuss the fundamentals characteristics classification and need of modern non traditional machining processes. Further the beam needs to be manoeuvred if required by the gun. This heat energy used to vaporize material at contact surface. Used with high power density to machine materials. Fig variation in power density with spot diameter of thermal beam process3 6. Ebm can be used for very accurate cutting or boring of a wide variety of metals. The cathode is generally made of tungsten or tantalum. Learn new and interesting things.

Download the seminar report notes ppt and journals on the topic unconventional manufacturing process. It uses a high velocity stream of electrons focused on the workpiece surface to remove material by melting and vaporization. This process is carried out in vacuum. Ebm is a high energy beam machining process electrical energy is used to generate high energy electrons the mechanism of material removal is primarily by melting and rapid vaporization due to intense heating by the electrons.
