“…The efficacy of the iPac strategy for erosion of other workpiece materials needs to be analysed. Also, the carbonaceous layer generation model described in [20] needs to be improved, to take into account the effect of different workpiece materials.…”

“…Regarding tool wear, it is observed that for a fixed value of pulse current, tool wear reduces up to an expected range with increased value of pulse-on time. Graphite additives do not influence surface properties remarkably, and therefore, no significant variations in surface properties are observed for different concentrations of the graphite [49,50].…”

Low removal rate, high power consumption, and dependency on conventional fuels (kerosene as a dielectric) are some premier issues that keep the sustainability index of EDM low, though it has huge acceptability and popularity mostly in aviation sectors and biomedical instrumentation to machine some extensively hard ferrous and nonferrous metal/metal alloys. Besides these, the thermal agitation inside the fusion/machining zone partially burns the dielectrics and tool-workpiece-metal, which evolve some oxides/monoxides. These evolved gases promote an unhygienic breathing atmosphere, which is very much harmful to the operator's health. Sometimes because of inadequate flushing pressure and velocity, carbon particles deposited inside the crater makes the spark unstable and releases carbon monoxide when the temperature exceeds its melting point. According to ISO 14000, every manufacturing process must be comprised of the sustainability criteria, which maintains a compromised balance between the economic, environmental, and social aspects, including the issue of the operator's health. But in real practices, it is very tough to maintain a stoichiometric balance between all these constraints. The article intensely focuses on the issue of emergence of gases during machining and tries to promote the utility of some alternative vegetable oil-based dielectrics, which are experimentally justified as a potent alternative of conventional kerosene. Apart from these, it includes some comparative talks on dielectric nature and their impacts on the responses and surface properties. Finally, this article highlights some compromise solutions which are probably capable of mitigating the hurdles to some extent, so that the sustainable machining can be encouraged in real sense.

“…It was noted that the use of an externally applied magnetic field aided material removal, increasing the MRR, while also restricting material migration from the electrode, decreasing TWR. Many more factors affect the TWR and surface finish such as deposited layers and applied current [29][30][31]. Interestingly, it was found that the shape of the magnet (as in the case of either bar or ring) did not have any noticeable effect on the performance of the process, and the MRR was only proportional to the strength of the applied field.…”

There has been an increasing interest in the penetration of magnetic field-assisted machining processes in the industries. Due to the ease of contactless forces, magnetic fields have proved extremely versatile and relatively low cost when considering the potential increase in productivity of existing machining processes that it can provide. In this overview, we review the recent achievements and developments in magnetic field-assisted machining processes and their applications. A wide variety of machining domains are examined including electro-discharge machining (EDM), micro-EDM, electrochemical machining, magnetic-assisted machining and many more. The advantages and limitations of each implementation and potential future research pathways are also discussed.
