    The unit on micro-machining (μ-machining) deals with the removal of material in very small quantities. Most of the time, the processes involved in μ-machining are used mainly for finishing purposes rather than correcting the dimensions. These processes are also used for making micro-miniature-components. During some of these processes, material is removed at atomic or molecular level specially in ion beam machining and elastic emission machining. In case of electron beam machining, material removal
