in conventional machining processes, are avoided. Ion-beam figuring is presented as an alternative for the final figuring of small ~,1-mm! optical components. The depth of the material removed by an ion beam is a convolution between the ion-beam shape and an ion-beam dwell function, defined over a two-dimensional area of interest.

Working Principle of Electron Beam Machining. In an electron beam machining, the electrons strike the workpiece with a high velocity. As the electron strikes the workpiece, the kinetic energy of the electron changes into heat energy. The heat energy so produced is used to melt and vaporize the materials from the w/p.
