ABSTRACT

Control parameters were used to reduce the defects that occur on the cylinder made by centrifugal casting. The defects of the centrifugally cast samples were decrease the strength and quality of the product. To avoid this defect full factorial design of experiments are proposed to run the procedure of centrifugal casting, to analyses the influence of process parameters on the defects during centrifugal casting three grade of aluminum alloy material is selected. Tests carried out on twenty-seven design of experiment characterized by a different variation of alloy material, Temperature, and speed of machine that solidify with water cooling process and analysis the defects of shrinkage and blowholes. The results of confirmation experiments reveal that grey–fuzzy hybrid method can effectively optimize an optimal combination of the process parameters. After that, the highest grey relation grade and highest GFRG parameters are selected as optimizing process parameter also compare the GRG and GFRG for their variation of a result of closeness.
