Abstract:

The Micro-structures are very difficult to produce by conventional machining methods and hence non-conventional machining methods are required for this purpose Present thesis work involves the use of Micro-machine tool to produce Microaperture on molybdenum work piece by using Microelectric discharge machining. Molybdenum is one of the most attractive high energy and power aperture materials due to its mechanical and physical properties, mainly its high melting temperature and relatively high thermal conductivity. A finite elementbased thermo-numerical model is developed for the Micro-EDM for the determination of temperature distribution in the zone of influence of single spark. The model is able to predict the shape and size of the crater that is formed by single spark as a result of the material removal.

Keywords:
