Laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process which can be applied for almost whole range of materials.

Electron beam machining conclusion. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. Illustration of laser matter interaction and material removal of short pulsed laser beam machining is given. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. 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. Laser beam is focussed for melting and vaporizing the unwanted material from the parent material. Further the beam needs to be manoeuvred if required by the gun. Difficulties of pulsed laser ablation is discussed. Today we will learn about laser beam machining principle working equipments application advantages and disadvantages with its diagram. Laser beam machining is a thermal machining process which uses laser beam to produce heat. 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. The high speed steel required for the cutting teeth is electron beam welded in a narrow strip to the main part of the blade which is in low carbon steel. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. Some examples of electron beam welded products are given below. Yunitha ratnadilla tri adhi kusuma 11313560tk37951 electron beam machining a.

Bi metal saw blades are produced in large numbers by electron beam welding. 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 welding ebw is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined. 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. Laser beam machining lbm. It is mostly used to drill holes in any shape. Electron beam machining ebm. In this chapter a overview on nano second pulsed laser beam machining has been discussed. This whole process takes place in vacuum chamber. The cathode is generally made of tungsten or tantalum.
