| Summary: | EDM has played a vital role in machining industry but with advancement of technology, alternative advanced methods of machining has been evolved. This technology have been proven more efficient than traditional EDM in terms of machining performance characteristics such as higher material removal rate (MRR) and improved surface characteristics of the machined surface with high tolerance quality products. Electric discharge machining is an advanced method of machining very hard conductive materials with complex geometries which are very difficult to machine by any other conventional method. In this present study a combination of conductive metallic powder (zinc) along with pressurized mist for powder mixed near dry electric discharge machining (PMND-EDM) has been utilized as a dielectric mixture in order to achieve higher material removal rate (MRR). The maximum material removal rate was found to be more than conventional EDM. |
