Ion beam machining ppt

WebIon beam machining is a molecular manufacturing (or atomic size stock removal) process based on the sputtering off phenomenon of work material by bombardment of energised ions of 1 to 10 keV and current density of 1 mill amphere/cm2. This process can be applied to manufacture ultra-fine precision parts of lectronic and mechanical devices. Web23 feb. 2024 · Laser Beam Machining is a thermal machining process which uses laser beam to produce heat and remove material from workpiece. In this machining, metal is removed from workpiece by melting and vapourizing of metal particles in a controlled from its surface using heat from laser.
