“…When T off is long, the time between effective machining pulses is often longer, thereby reducing MRR as less intense sparks are produced. 28 The 3D interaction graph between current and servo voltage is shown in Figure 3(d). The MRR was decreased from 6.993 mm 3 /min to 5.497 mm 3 /min when the current was set to a value of 6 A, and the SV was adjusted from 40to 60 V with a vibration of 20000 Hz.…”

Nitronic-50 stainless steel is a high-strength and corrosion-resistant austenitic premium steel. It requires improved surface characteristics due to its wide use in various applications like fasteners, marine hardware, hydroelectric-power turbines, pressure vessels, etc. This work focuses on machining hard-to-machine Nitronic-50 steel is unconventionally machined using constant frequency ultrasonic-aided low-speed wire electrical discharge machining (USV-LS-WEDM) to enhance its machined surface integrity. This method achieves effective results when cutting high-strength materials with intricate shapes. Material removal rate (MRR) and surface roughness (Ra) were measured by considering inputs such as servo voltage (SV), pulse off time ( Toff), pulse on time ( Ton) and current (I) with an ultrasonic-vibration range of 20,000 Hz. The appropriate selection and usage of LS-WEDM parameters is a challenging process and is done with parametric analysis. The MRR of Nitronic-50 was enhanced with an increase in Ton and I along with a reduction in Toff and SV. Surface roughness (Ra) decreased with a gradual reduction in Ton, I, and an increase in SV. The USV-WEDM was compared with a stand-alone WEDM indicating that the MRR for USV-WEDM was improved by 12% and the Ra was decreased by 9% due to effective distribution of spark discharges, which increased material erosion and redistribution of molten metal characteristics. Machining quality for hard-to-machine Nitronic-50 steel was certainly enhanced via hybrid ultrasonic vibration with the existing LS-WEDM.

“…To conduct the desired activity, the principle consists of converting water's available pressure energy into kinetic energy by passing it through a small hole (orifice) [2]. Abrasive performance was discovered to be significant while taking cuts, and proper abrasive recharging improved the penetration depth of waterjets at a lower cost [3]. In addition, a good surface finish was observed when AWJC of a metal alloy was compared to AWJC of pure metal as a parent [4].…”

The current work focused on studying the effect of process parameter on kerf width in Wire EDM using molybdenum wire electrode. Pulse on time, pulse off time, Servo voltage and wire feed were selected as a process parameter for design the DoE in Response Surface Methodology. It was observed that electrical parameters chosen had a significant impact on the Kerf Width. Pulse on time is the most important electrical characteristic for Kerf Width. Higher duration of the spark causes the job to shift dimensions. Utilizing Design Expert's point prediction functionality, model validation was carried out.
