“…Presently, highly sophisticated machining techniques were developed to machine the advanced composite materials, notably few techniques like water jet machining, ultrasonic machining, 4 laser machining, 5 and electric discharge machining. 6 Water jet machining is the most preferable method to machine polymer composites due to its superior advantage over other machining properties. 7 Through abrasive water jet machining (AWJM), composites can be processed by cutting, drilling, and milling.…”

Composite materials have taken an imperative place in the material system because of their unique performance in various specialized applications. Fiber inclusion and the heterogeneous property of composites make it more difficult to machine with the conventional machining process. However, several nonconventional methods have been adopted for machining composites, in which abrasive water jet machining (AWJM) was proven to be more effective and a preferable technique in machining of fiber-reinforced composite material. This review article is intended to highlight and categorize the machining performance of the fiber-reinforced composites on machining with AWJM process.

“…[22] noticed that MRR was significantly increased up to a certain limit of applied current and voltage. Simultaneously, it rises with the increased value of electrode peripheral speed and then again decreases when tool rotation, acoustic emission, and gap flushing techniques are employed Kerosene Cu/steel/ brass/Al CFRP Islam et al [23] observed that during the EDM operation of CFRP with different electrode materials like Al, Steel, and Cu, minimum unwanted burrs are found when machining was pursued with copper tool Brass Cu Prihandana et al [24] employed dielectric vibration to achieve improved MRR, because ultrasonic vibration helps additive dust particle to mix properly inside the entire volume of the dielectrics. It was observed that the amount of carbon wear particles on the machined surface was comparatively less in case of powder-mixed kerosene when compared to pure kerosene, which was detected by X-ray dispersive (XRD) analysis Kerosene Ti Cu-Be Yildiz et al [25] applied the concept of heat transfer and simulation technique to predict the optimum MRR with minimum possibilities of white layer formation TiC Wang et al [26] Niamata et al [30] assessed the performance of Al alloy using both kerosene and distilled water as dielectrics and observed that kerosene gives more stable and efficient machining performance than distilled water.…”

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.

“…In this study, they used the small cylindrical tool and low discharge energy pulse for deburring operation. Islam et al [82] introduced the micro-EDM process as a deburring method during the drilling of carbon fiber-reinforced plastic (CFRP) composites. Deburring was done at various capacitances using different electrodes (steel, brass, aluminum and copper) materials, and as a result, it was reported that the copper electrode was more effective than the three other electrode materials.…”

Micro-electrical discharge machining is an indispensable tool to manufacture the component or parts of components at the micro-level with reasonable accuracy and precision. This article reports a comprehensive overview of micro-EDM along with their recent trends and key challenges. The sparking phenomenon, physical principle of material removal, process capabilities and flexibility with the other machining process are discussed in the initial part of the paper. Major development issues associated with nano-EDM are reviewed, and suggested solutions are proposed. Research and technology gaps enabling the transition from micro-EDM to nano-EDM are examined. The impact of discharge power technology and dielectric circulation is explored. Moreover, this review article explores the sustainability of the system (micro-EDM) through green manufacturing. A state-of-the-art has been studied in various aspects of micro-EDM. The promising future research scope is also noted in micro-EDM as well as in nano-EDM based on the electrical discharge.
