Investigation Of Effect Of Laser Beam Machining Lbm

Basically electron beam machining is also a thermal process.

Electron beam machining process parameters. 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. Yunitha ratnadilla tri adhi kusuma 11313560tk37951 electron beam machining a. Sunil pathak 2 process principle continued the process of heating by an electron beam can be used for annealing welding or machining electron beams are focused to a point within 10 200 mm by means of magnetic fields and power density can be as high as 65 x 1012 wmm2 ebm is a precisely controlled vaporization. Meaning of electron beam machining ebm. Shows an electron beam gun which is the heart of any electron beam machining facility. The accelerating voltage the beam current pulse duration energy per pulse power per pulse lens current spot size power density 16. 160000 kmsec focused stream of electrons which are focused magnetically upon a very small area. This whole process takes place in vacuum chamber. Here a stream of high speed electrons impinges on the work surface whereby the kinetic energy transferred to the work material produces intense heating. As such one has to adopt experimental. 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 materialebm 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. Electron beam machining equipment fig. It is mostly used to drill holes in any shape. Sunil pathakebm process by dr.

Control parameters optimization of laser beam machining using genetic algorithm ruben phipon1 bbpradhan2 1 mechanical. This will generate high heat energy and melts and vaporize metal from work piece. Electron beam machining ebm. Abstract to improve and optimize the responses of a laser beam machining process the various input machining control parameters are to be set at an optimal value. Depending on the intensity of the heat thus generated the material can melt or vaporize. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. Surface finish is better and kerf width is narrower than those for other thermal cutting processes. Electron beam process parameters the process parameters which directly affect the machining characteristics in electron beam machining are. In this process the material is removed with the help of a high velocity travelling at half the speed of light ie. Ecm process by dr.
