Resumen

Wire electrical discharge machining (WEDM) is a thermal spark erosion type cutting process used for precisely machining parts with intricate shapes and sharp edges that are difficult to machine by the conventional machining processes. The WEDM process is derived from conventional EDM sparking phenomena utilizing the noncontact type technique for material removal. From the time of introduction of the process, WEDM has emerged as alternative for production of micro-scale parts with the higher accuracy in dimensions and surface quality. MMCs are advanced materials with high specific strength, better wear resistance, and high thermal expansion coefficient due to composing one metal in other metal matrix. Machining parameters such as; pulse on/off time, peak current, servo voltage, wire feed, wire tension etc. are required at optimal value for performance measures like Material Removal Rate (MRR), Gap current, Surface Roughness (SR), Kerf characteristics, etc. improvement. In past years, researchers have worked for enhancement and optimization of WEDM performance measures using various optimization methods like Taguchi, Response Surface Methodology (RSM), etc. This paper also shows the feasibility of the different methods of obtaining the optimal machining conditions. This literature review helps to identify the significant process parameters out of available process parameters for machining of MMCs. In this paper research work of various researchers has been discussed with how much work has been done and the scope for the optimization of parameters for the responses during MMCs machining on WEDMCite this Article Pujara JM, Gohil AV.
