Abstract

This paper presents an experimental investigation of electrode diameters on surface roughness of mild steel in Wire Electrical Discharge Machine (WEDM). There are two objective of this project that needs to be accomplished. First to determine the relationship between mild steel surfaces roughness against brass wire diameters and to recommends the best electrode diameter to machine mild steel work piece material. 5 work pieces are machining and 15 readings of surface roughness are taken for every size of diameter of wire. After gathered all data or value that needed, two analysis are been performed. From the t-test Minitab software analysis, the smaller diameter of wire is proving to be the lower surface roughness. The p-value indicated that there is significant difference between 0.1 Omm and 0.20mm diameters of brass wire and surface roughness of the cutting part of mild steel work piece with using 95% confident intervals. The analysis from t-test also indicated the best wire is brass wire with 0.1 Omm diameter.
