“…The stimulus of changed process parameters on the white layer thickness was studied, providing insights into optimizing the machining parameters for enhanced EDM performance [6]. Few studies were focused on Inconel 718, a widely used Ni-based superalloy; this research investigates the white layer formation during wire EDM [7]. The authors discovered the characteristics of Ti-6Al-4V with rotary ultrasonic-assisted EDM [8].…”

“…It was concluded that the PW and PI are the most important factors that enhance the WEDM performance [15]. The CR and surface finish of cryogenically cooled aerospace component material had been improved in EDM experiments [16]. The effects of various cutting parameters on surface cracks and white-layer formation have been analyzed using metal powder mixed dielectric fluid in the WEDM.…”

In this research, influences of cryogenically treated Inconel 718 work material in near-dry wire-cut electrical discharge machining (WEDM) characteristics have been studied using argon-mist (mixing of pressurized argon gas and minimum amount of tap-water) and a reusable Molybdenum wire tool. The effect of cutting parameters (pulse width (PW), spark current(C), pulse interval (PI), and flow rate(F)) on surface roughness (SR) and cutting rate (CR) and using Box-Behnken response surface analysis. It was observed that CR and SR are increased by increasing PW, and C; conversely, reduced by increasing PI. The technique for order of preference by similarity to ideal solution (TOPSIS) method has been utilized to estimate the best parameters’ settings for improving both machining characteristics. The optimum CR (9.81 mm3/min) and SR (1.9 µm) have been obtained by optimum settings of 4 Ampere spark current, PW of 20µs, PI of 72µs, and 18ml/min of the flow rate of mixing water using the TOPSIS method. The best settings of cutting parameters obtained from the TOPSIS method were considered to compare the near-dry WEDM performance using cryogenically treated/ untreated work materials. It was observed that CR and SR of the cryogenically treated work material are 9.17% increased and 21.58% reduced than the untreated work material due to an increase in electrical and thermal conductivities.

“…Recently, the effect of cryogenic treated and untreated tool on EDM tests have been performed out on Inconel-625 workpiece material. Influences of controlling factors on MRR and surface roughness have been investigated [39]. The electrode wear ratio and MRR were examined on a conventional EDM process using the TOPSIS approach [40].…”

In this research, the mixing of compressed air with the minimum quantity of water is used as a dielectric medium and the cryogenically cooled molybdenum wire is used as a tool in wire-cut electrical discharge machining (WEDM) to encourage the eco-friendly production, called cryogenically cooled near-dry WEDM process. The nitrogen gas-cooled wire tool is utilized to cut the Inconel 718 alloy workpiece to prevent wire breakage and maintain enough electrical conductivity. The preliminary experiments were conducted to compare wet, dry, near-dry, and cryogenically cooled near-dry WEDM processes. It was revealed that cryogenic cooled near-dry WEDM is better performance than dry, near-dry WEDM except for the wet process. The systematic experiments of eco-friendly cryogenically cooled near-dry WEDM have been conducted to analyse the effect of input factors like spark current, pulse-width, pulse-interval, and mixing water flow rate on material removal rate (MRR) and surface roughness (SR) using Box–Behnken method. The fitted models and response surface graphs were developed to analyse the influences of input factors on each response parameter. It was concluded that MRR and SR of cryogenically cooled near-dry WEDM are increased by maximizing spark current, pulse-width, and flow rate, conversely, both responses were decreased by increasing pulse-interval. The technique for order of preference by similarity to ideal solution (TOPSIS) technique has been applied to predict the best combination of input factors for satisfying the optimal values of both responses.
