“…Such a minor resistance value infers that the electricity can be easily conducted at a reasonably high rate. Other supreme characteristics of Cu include excellent corrosion resistance, nonmagnetic behavior, high ductility, and it can also act as a strong antibacterial agent [51]. The aforesaid feature makes it a preferred choice in this investigation.…”

NetZero advancements for the manufacturing industry are aspiring for precision machining of difficult-to-cut materials with a high degree of accuracy, particularly for Ni-based super alloys while meeting climate protocols. The applications and properties of the foregoing materials warrant the usage of the electric discharge machining (EDM) technique. However, given the rising scarcity of resources, there is a compelling need to make this process sustainable. The standard dielectric (kerosene) employed in EDM is hazardous to one's health and fails in terms of long-term productivity. As a result, an effort has been made in this study to evaluate the potential of biodegradable dielectrics, at different copper powder concentrations for sustainable machining of Inconel 600. This investigation evaluated three powder concentrations (0.5, 1.0, and 1.5) g/100 ml for each dielectric. Output responses including electrode wear rate and overcut explicitly aid in ensuring long-term productivity. For example, EWR represents economic assessment, while overcut determines dimensional accuracy. The full factorial design method was used in the experiments, followed by a full statistical examination encompassing, parametric effects and interactions, and signal-to-noise ratio. The findings of this study revealed a decreased EWR (2.69 mm3/min), as well as a minimal overcut (0.33 mm). In case of EWR, about 39% variation in the magnitude has been noted when dielectrics have been varied, whereas approximately 30.9% variation in EWR was observed against the change in the powder concentration. For overcut, the influence of the dielectric on the response magnitude has been further improved as it produces about 61% variation in the OC value. However, the impact of the change in powder concentration for overcut is 8%. It was found that Amla oil with a powder concentration of 0.5 g/100 ml produced the least tool wear, but Sunflower oil at minimum powder concentration (0.5 g/100 ml) produced the minimum overcut. As a result, the combined effect of all of the aforesaid strategies results in more sustainable and dimensionally accurate machining.

“…In addition, the flushing pressure can be decreased by increasing the diameter of the internal through hole, which also weakens the flushing [78]. Yilmaz and Okka [96] studied the effect of single and multi-channel electrodes and concluded that using a single channel electrode led to higher MRR and lowered TWR when machining Inconel 718, whereas the multichannel could provide a better "cooling" effect, resulting in less removal of melted material [97]. Wang and Wang [98] found that by using a rotary electrode with eccentric through holes (Fig.…”

Electrical discharge machining (EDM) is one of the most widely used non-conventional methods to machine electrically conductive materials in the manufacturing industry because of its strong capability in machining difficult-to-cut materials irrespective of their strength and hardness. Electrical discharge drilling (EDD) is an important variant of EDM. Due to the limitation of conventional drilling processes, special holes, particular those with high aspect ratios on hard-to-cut materials, can only be drilled by EDD. Extensive research has been carried out to improve the efficiency and quality of the EDD process by using different approaches, such as assisted EDD and powder-mixed EDM drilling aiming to improve the material removal rate (MRR), tool wear rate (TWR), surface quality and accuracy. This paper provides a comprehensive review of the EDD process. Different methods were compared; the advantages and disadvantages of each process were summarised; state-of-the-art technologies and the latest development were introduced, and research trends and new directions were presented.

Hybridization of aluminium matrix composite is with a view to offset the properties deficient in one composite reinforcement. The present investigation involves a comparative study of AA6063 matrix composites with single reinforcement of Al2O3, SiC, graphene respectively and various hybridized proportions of the same reinforcements. Physical (density and %porosity) and mechanical (tensile strength, fracture toughness, %elongation, elastic modulus, etc.) properties of composites developed via solidification processing technique were evaluated. The porosity of all the composites falls below the maximum acceptable limit for cast metal matrix composite. Maximum values for UTS, %elongation and absorbed energy at maximum stress was obtained by hybrid composite with 4wt% Al2O3, SiC and 2wt% graphene, while the composite with the highest single reinforcement of graphene have the highest value for elastic modulus and fracture toughness. Numerical optimization results show that a matrix and hybrid reinforcements contents of AA6063 (91.413wt.%), SiC (3.679wt.%), Al2O3 (0.277wt.%), and graphene (4.632wt.%) respectively, will result in optimal values for the evaluated properties.
