4. Introduction & Definition2
 Electron beam Machining (EBM) is a process
where high velocity electrons concentrated into a
narrow beam are directed toward the work piece
surface to remove material by melting &
vaporization.
 Also known as “Electro optical thermal process”.
 Use high power density
