Electron beam is generated in an electron beam gun. Electron beam gun provides high velocity electrons over a very small spot size. Electron Beam Machining is required to be carried out in vacuum. Otherwise the electrons would interact with the air molecules, thus they would lose their energy and cutting ability. The thermal effect of Electron Beam that specially depends on the electrical arc, Electron type and temperature field of it in work piece is the main key of analysis and optimization of this process, from which the main goal of this paper has been defined. Numerical simulation of process by ANSYS software for gaining the temperature field of work piece, the effect of parameter variation on temperature field and process optimization for different cases of Electron Beam are done. The influence of the process parameter for each mode on the dimensions and shape of the machining and on their ferrite contents is investigated.
