Explain the Electron Beam Machining

Electron Beam Machining is the metal removal process by a high velocity focused stream of electrons which heats, melts and vaporizes the work material at the point of bombardment.
The production of free electrons is obtained from thermo-electronic cathodes wherein metal are heated to the temperature at which the electrons acquire sufficient speed for escaping to the space around the cathode.
The acceleration of the electrons is carried by an electric field while the focusing and concentration are done by controlled magnetic fields.
The kinetic energy of a beam of free electrons is transformed into heat energy as a result of the interaction of the electrons with the work piece material.
EBM is a thermo-electric process.
