<div class="section abstract"><div class="htmlview paragraph">Wire Electrical Discharge Machining (WEDM) is a widely used manufacturing method that is employed to shape complex geometries in conductive materials such as cupronickel, which is highly regarded for its resistance to corrosion and ability to conduct heat. The aspiration of this investigation is to improve the effectiveness and accuracy of Wire Electrical Discharge Machining (WEDM) for cupronickel material by utilizing the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) optimization method. The study analyzes the impact of WEDM parameters, specifically pulse-on time, pulse-off time, and discharge current, on important machining outcomes such as surface roughness, material removal rate. Experimental trials are performed to collect data on these parameters and their corresponding machining characteristics. The TOPSIS optimization method is utilized to determine the most favourable parameter settings by evaluating each parameter combination against the ideal and anti-ideal solutions. This method determines the parameter configuration that maximizes machining efficiency and accuracy while minimizing electrode wear. The efficacy of the TOPSIS-optimized WEDM process is assessed using statistical analysis and compared to the baseline outcomes. The methodology showcases its efficacy in improving the quality and productivity of machining for cupronickel material, providing manufacturers with a systematic approach to attain superior machining results. The proposed TOPSIS optimization method offers a valuable tool for optimizing WEDM parameters, allowing manufacturers to enhance productivity and quality while minimizing production costs in cupronickel machining operations. This study enhances the comprehension of WEDM processes and provides valuable guidance for improving machining operations in different industrial sectors.</div></div>
