Abstract

Brass wire electrode with size 0.2 mm is used in Wire Cut Electro Discharge Machine (EDM) for different work piece in similar size at four various current values. Objective which achieved in this project are relationship between parameter of Wire Cut EDM (current) with different material as work piece. The material which used as workpiece in this experiment is copper, mild steel, brass and aluminium. This experiment are divide by two parts where in first part, machining test are progressed to three surfaces with different current value for each surface. In second part, machining test is progressed with change the material as work piece. From both experiment, surface wish will be produced are not depend only to current value which used during machining but then have relationship with type of material as work piece. After that. the research will be making for relationship between current value, material used and surface finish. This research encircles suitability around material usage with current usage and surface finish which will produce. As a result, we can known that the certain current only suitable for a certain material only but then not suitable for others material. Thus too with good surface finish, it is depend to current suitability which used during machining process.
