This paper emphasises the effect of the surfactant in the PMEDM process. The preparation of nanofluid is done by mixing and sonicating thoroughly into the deionised water is discussed. The effect of varying the graphene nanopowder concentration into the dielectric is also discussed. Also, the effect of surfactant SDS and CTAB in the machining process is elaborated at 0.1 and 0.2g per 800ml concentration. MRR improved by 21.27% and roughness by 18.91% at 0.2g and 8µs, 2A and 50V in 800ml deionised water. SDS provide better MRR and low roughness compared to CTAB at higher peak current and higher pulse on time Simultaneously, the addition of surfactant into the dielectric medium reduces the performance of the EDM process. The MRR varies from 21mg/min at 0g graphene to 45mg/min at 0.2g and then 31.81mg/min at 0.2g with 0.1g SDS, 43mg/min at 0.2g SDS, 28.33mg/min at 0.1g CTAB and 30mg/min at 0.2g CTAB. Debris size also varies with the input parameters.

ABSTRACT Inconel 718 in a nickel-based superalloy has excellent mechanical properties such as high tensile and impact strength, excellent oxidation, and corrosion resistance. Unlike most superalloys, it is suitable for the application of high strength in cryogenic as well as at elevated temperature. In this present work, the machinability of Inconel 718 through the EDM process and the performance of graphene nano as a dielectric medium are investigated. Therefore, the concentration of the graphene nanofluid in deionized water is investigated. The influence of the three major process parameters is studied the EDM. The technological characteristics chosen for the study of the performance of graphene nanofluid are MRR, surface roughness, and TWR. The response data confirm the significant influence of those selected process parameters on the yield. The graphene nanofluid shows improvement in machining performance. The waveform identifies stable spark phenomena in the NPMEDM process. The machined surface morphology is examined through field emission scanning electron microscopy (FE-SEM) images.

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.
