Experimental and response surface methodology investigation of cast material obtained by melting and recycling of chips

Abstract

In this study, it is aimed to draw attention to the new materials and recycling produced by the melt-casting process of chips in industry. For this purpose, the aluminum 5000 series material with 90 HB hardness was turned. The chips obtained by turning were melted in our own melting furnace and molded as a cylinder. The hardness value of the material obtained by casting method was measured as 95 HB. Materials were examined by surface microscopy. Experimental design, analysis of surface roughness values of normal and cast material, regression equations, coefficients of determination, optimum point, cutting parameters interaction graphs were carried out with response surface methodology (RSM). It was concluded that the surface roughness values decreased in the casting material. In order to determine this reduction, the surfaces of the chips and materials were examined. In prediction experiments, it was observed that the RSM model yielded 90% reliability.
