Abstract

Highlights: To achieve dimensional accuracy and surface finish on casting process is difficult task. Aluminium 6082 and silicon is fabricated through lost foam casting method. The different input constraints such as pouring temperature, slurry viscosity and cooling time were considered. The tensile strength was evaluated for the fabricated specimens. Taguchi technique is applied to determine the optimal factor. Abstract: The current scenario is to achieve dimensional accuracy and surface finish of the casting components which is identified to be a difficult task. It can be achieved through lost foam casting process. This casting process eliminate the difficulties in design considerations of casting products. Lost foam casting process has provided the quality of components through flexible manner. It's being used to create complex metal pieces with less production time. In this experimental investigation, aluminium 6082 and silicon is fabricated through lost foam casting method. During casting process, the different input constraints like pouring temperature, slurry viscosity and cooling time were considered. The tensile strength is evaluated for the fabricated specimens. Taguchi technique is applied to determine the optimal factor. The contribution of factor is confirmed through variance analysis. The effect of factor and its correlation were studied through interaction plot.
