Optimization of Machining Parameters in Turning Agricultural Waste based Aluminium Hybrid Composite

Abstract

The purpose of the present research is to identify the suitable turning parameters for rice husk ash and molybdenum disulfide reinforced aluminium composite. The parameters that are taken in to consideration for the study is rice husk ash (RHA) percentage, speed and feed while turning in which the objective function is surface roughness. The turning operation with three parameter consideration is designed through Taguchi method and the L9 array is selected. The turning operation is performed in high speed computer numerical controlled lathe and roughness is measured through SJ201 mitutoyo tester. The results confirmed that the machinability of the aluminium is greatly affected by the reinforcement incorporation. Further, the feed rate and speed also influences the surface roughness in significant amount.
