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.
