Abstract

Electrical Discharge Machining (EDM) is a process of metal machining in which a tool discharges thousands of sparks to a metal work piece. The main purpose of this project is to compare surface roughness of tool steel material using zinc coated brass and brass electrode wires and to recommend the best electrode diameter to machine tool steel work piece material application. There are three objective of this project that needs to be accomplished. Firstly is to compare the surface roughness of tool steel material using zinc coated brass and brass electrode wires. Secondly is to recommend the best electrode diameter to machine tool steel work piece material application. Thirdly is to study the effects of feed rate to the surface roughness. 3 work pieces are machining and 15 readings of surface roughness are taken for every size of diameter of wire. By using the Minitab software, the data in each objective is done. As a conclusion, the best wire for both types is zinc coated brass. Then, the best diameter of wire is 0.10 mm based on their surface roughness result. Next, according to feed rate changed, it is not much a distinction in effect of surface roughness value. In addition, take an over reading on each sample to be a correction if have any error occurred.
