Effect of Wire EDM Cutting Parameters for Evaluating of Additive Manufacturing Hybrid Metal Material

Hybrid metal materials produce through Additive Manufacturing of Indirect Selective Laser Sintering (ISLS) process have been highly interested by the researchers and industries nowadays in producing near net shape metal components. These materials have a strengthening affect such as high thermal conductivity, good wear resistance, high corrosion resistance, good insulation, high-strength material which applicable in industry of aerospace, automotive, tooling manufacture and also in biomedical industry. The material tested is FeCuSn hybrid metal material which machined by wire electrical discharge machining (WEDM). However, there are some difficulties in generating a model that can accurately correlate the input parameters of WEDM with the responses because the parameters setting are restricted with the operator's experience. Hence, there are no specific parameters for hybrid metal materials in WEDM. The machining parameters such as pulse-on time, pulse-off time, peak current and voltage will be reset according to the Design of experiment (DOE) while the analysis will be focused upon the effect of the working surface and the hardness of work material. Thus, the final result of optimization parameters was established. The objective of this paper is to highlight those important parameters to be considered in wire cutting process of FeCuSn hybrid metal material produce by Additive Manufacturing of Indirect Selective Laser Sintering process for fabricating the near net shape metal component.
