Effect of composition and grain structure on machining performance in EDM-A review

© Published under licence by IOP Publishing Ltd. Nowadays, MMC materials are in trend. EDM process fulfills the requirement of manufacturing product of MMC. MMC materials have a wide range of composition. The machinability of materials varies with the composition and grain size. The machining property of metals and alloys have been tested on EDM. But testing machinability of each MMC material on EDM is very difficult due to the variation in composition, composition percentage and grain structure. This difficulty can be eliminated by a universal equation. Determining the effect of composition, composition percentage and grain structure in EDM and plotting with respect to machinability of the material will give a universal equation. This equation will be valid for all materials machined by EDM process. Hence, this will leads to determine the theoretical machining performance of the new MMC material. It will decrease the sample testing time for machinability.
