Abstract

In this study, the Wire Electrical Discharge Machining (WEDM) process for OHNS (Oil Hardened Non-Shrinking) steel, a high-performance material frequently used in the production of dies, punches, and precision tooling components, is optimized parametrically and validated experimentally. A continuously moving wire electrode and a sequence of electrical discharges are used in WEDM, a non-traditional machining method, to erode material and produce intricate and precise profiles, particularly in materials that are challenging to machine. Using a Taguchi L9 orthogonal array design, a structured experimental approach will be used to gather data under controlled conditions. This approach helps to reduce the number of experiments while offering important insights into the behaviour of the process. To ascertain the impact and interplay of different process parameters on the output responses, the experimental results will be statistically examined using Analysis of Variance (ANOVA). Additionally, the process’s robustness under various conditions will be assessed using Signal-to-Noise (S/N) ratios. To guarantee the accuracy and repeatability of the findings, confirmation experiments will be used to validate the optimized parameters that were determined by the analysis. The purpose of this study is to help with the accurate and efficient machining of OHNS steel using WEDM by providing insightful suggestions for industrial applications where precision, surface integrity, and productivity are critical. The findings will serve as a reference for engineers and manufacturers to fine-tune WEDM processes for high-performance tool steels. This study’s main goal is to identify the ideal combination of process variables that result in better machining performance, specifically wire tension, servo voltage, pulse on-time, and pulse off-time. Critical response characteristics like surface roughness, material removal rate (MRR), and dimensional accuracy will be used to evaluate the machining process’s quality.

Keywords: WEDM, OHNS, pulse on-time, pulse off-time, servo voltage, wire tension, MMR, ANOVA
