Abstract

Electrical discharge machining (EDM) is a machining option that was well-established for manufacturing purpose especially for high hardness material parts or complex in geometry that is extremely difficult to be machine by using conventional machining. This machining process alternative that required no contacts have attracted a significant amount of research interest. EDM process is based on thermoelectric energy between the electrode and work piece. A discharge of pulse occurs in a small gap between the electrode and the work piece will removes the targeted part of by the mean of melting and vaporisation. Basically, EDM can be divided into two major types, wire cutting machine and die sinking. In wire cutting EDM, the sparks is generated between a thin wire and work piece. For die sinking, the work piece which is formed by duplication of a shaped tool electrode is fully immersed in the dielectric fluid. This project paper objective is to research and develop the numerical model of the specimens by using the EDM process by including the quite element technique. The model then will be analyse in terms of hazard affected zone (HAZ), material removal rate (MRR), and the view of model of after the machining process done. The data of MRR that been obtained from the model will be compared with the data obtained from actual experiment and previous research. The methodology of this project will be preliminary data gathering, model development, thermal analysis, actual experiment and result’s validation. In the end, this project will be able to present the thermal model for single and multi-spark EDM process by using CAD / CAMS software, ANSYS.
