“…This situation is consistent with the literature (Tosun et al, 2004). Also; according to some researchers, it has been concluded that the most effective parameter in processing with WEDM is the pulse-on time (Rajyalakshmi and Ramaiah, 2013;Thejasree et al, 2021;Natarajan and Arunachalam, 2011). Natarajan and Arunachalam stated that pulse-on time was the most important parameter in the ANOVA results for GRG for multiple performance characteristics (Natarajan and Arunachalam, 2011).…”

“…They stated that pulse-on time is the most important process parameter for better performance characteristics. They stated that the most effective machining parameter for MRR is pulse-on time and as the pulse-on time increases, the amount of electrons acting on the workpiece will increase, so more material will be eroded from the workpiece surface (Thejasree et al, 2021). Kumar and Singh (2021) examined the impact of process parameters such as pulse-on time, open circuit tension, wire tension and wire feed rate on MRR and Ra in WEDM of IN718 superalloy using brass wire.…”

PurposeInconel 718 (IN718) is a high-performance nickel-based superalloy with high oxidation-corrosion-temperature resistance, high strength (tensile, fatigue, creep and rupture), durability, toughness, hardness and dimensional stability, which is difficult to machine with traditional fabrication methods. To overcome these difficulties, wire electrical discharge machining (WEDM), one of the modern manufacturing methods, is used.Design/methodology/approachMain performance criteria in WEDM; material removal rate (MRR), cutting speed, surface roughness, cutting width (kerf) and wire wear rate. In this study, the effect of processing parameters on kerf and MRR because of processing IN718 in WEDM was investigated. Machining parameters, voltage, wire feed rate and dielectric fluid pressure were determined. Deionized water was used as a dielectric fluid and 0.3 mm brass wire was used as wire in the experiments. Gray Relational Analysis (GRA), which is one of the multi-criteria decision-making methods, has been applied for the optimization of the machining parameters in the cutting process with the WEDM. Analysis of variance (ANOVA) was used to determine the effect percentages of the cut-off parameters.FindingsThe parameter with the highest effect was determined as tension with a rate of 76.95% for kerf and 91.21% for MRR.Originality/valueThe novel approach uses Taguchi-based GRA optimization as a result of cutting IN718 with WEDM, reducing cost and time consumption.
