Electron Beam Machining Wikipedia

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. Electrical discharge machining is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques.

However while the sem uses a focused beam of electrons to image the sample in.

Electron beam machining wikipedia. In current usage. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. The beam cross section is then focused and directed toward the work piece creating heat and vaporizing the material. Edm typically works with materials that are electrically conductive although methods have also been proposed for using edm to machine insulating ceramics. 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. A collaborative effort to improve the coverage of metalworking on wikipedia. 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. This video is unavailable. Focused ion beam also known as fib is a technique used particularly in the semiconductor industry materials science and increasingly in the biological field for site specific analysis deposition and ablation of materialsa fib setup is a scientific instrument that resembles a scanning electron microscope sem. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. Surface finish is better and kerf width is narrower than those for other thermal cutting processes. Jump to navigation jump to search. Since the advent of new technologies in the postworld war ii era such as electrical discharge machining electrochemical machining electron beam machining photochemical machining and ultrasonic machining the retronym conventional machining can be used to differentiate those classic technologies from the newer ones. Electron beam machining can be used to accurately cut or bore a wide variety of metals. Electron beam machining is a process in which high velocity electrons are concentrated into a narrow beam with a very high planar power density.
