Electron Beam Machining Parameters

Depending on the intensity of the heat thus generated the material can melt or vaporize. Abstract laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process.

Difference Between Edm And Ebm Electric Discharge

Thus the work piece to be machined is located under the electron beam and is kept under vacuum.

Electron beam machining parameters. 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. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. 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. Electron beam machining ebm electron beam machining is a thermal nontraditional process uses electrical energy to generate thermal energy for removing material. This is why machining fragile and brittle materials is obtainable using this method. Rayate pg student kkwagh institute of engineering education and research nasik maharashtra india. Electron beam machining does not apply any cutting force on the workpiece thus very simple work holding is required. Basically electron beam machining is also a thermal process. Electron beam welding was used for joining al6061 t6 precision machined cylindrical sections. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. 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. The cathode is generally made of tungsten or tantalum. As electron beam machining is grouped under the thermal category it is natural to have thermal damages as part of the result. Otherwise the electrons would interact with the air molecules thus they would lose their energy and cutting ability. One commonality of these electron beam welders is that all beam parameters and all mechanical axes are numerically controlled either by a plc or a cnc.

The high energy focused electron beam is made to impinge on the. Ebm can be used for very precise cutting or boring of a wide variety of metals. Electron beam machining ebm. As with any modern machine tool all process parameters can be stored by their respective part numbers and retrieved at a later date. Multi objective optimization of laser beam machining process parameters pj. Further the beam needs to be manoeuvred if required by the gun. 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. Here a stream of high speed electrons impinges on the work surface whereby the kinetic energy transferred to the work material produces intense heating. The welded assembly exhibited a minimum amount of distortion but a better understanding of the effects of several key welding parameters on the structural integrity of the weld was required. Electron beam machining is required to be carried out in vacuum.
