Comparison of surface roughness for different combinations of workpiece and electrode materials in wire EDM process

Abstract

Wire Electro Discharge Machining (EDM) is a metalworking technique that extracts material from a conductive work piece by using electrical corrosion. The goal of this study is to find the best Wire-EDM material for manufacturing components for the aerospace and automotive industries. Input process parameters that are considered include wire feed rate, pulse on time, pulse off time, peak current, and servo voltage. The performance parameters are surface roughness. This experiment also employs a variety of wire materials, such as half hard brass wire and Zn-coated brass wire, to determine the best wire material for achieving the best response. According to the findings, SAILMA 350 material is superior to Titanium material for manufacturing industry components, and machining SAILMA 350 materials to achieve good quality and lower costs with Zn-coated brass wire is preferable.
