Abstract

The aim of this research is to study the affect parameter cutting of Wire Electrical Discharge Machine (WEDM) of surface roughness, tolerance and machining time for aluminum plates. The material use in this experiment is Aluminum 5083. For this assessment, the experiments were conducted on the Mitsubishi RA 90 wire electrical discharge machine. Design of Experiment (DOE) will be employed to determine the significance of the affecting parameters toward the response variables. The parameters studied include voltage gap, peak current, wire speed, and wire tension. The response variables investigated are the surface roughness, tolerance width and machining time. The surface roughness obtain is measured using Mitutoyo S-J 301, while the tolerance of the cutting is measured by micrometer. The roughness profile used in this study is roughness average, (Ra). The significance of the study is to achieve the desirable surface roughness and the resulting tolerance after cutting by wire EDM is done on the workpiece. A better surface roughness can improve the quality and the value of the component produced in the manufacturing industry.
