Abstract
The influence of spindle speed, feed rate, and depth of cut of alumina particle on lowering surface roughness during turning of Al7129/TiC/B4C hybrid composite is investigated in this study. The composite is turned using a TiN coated solid carbide tool. Taguchi's experimental design concept is utilized to optimize three tiers of design parameters for improved for better surface finish. The results of the experiments and the microstructure of the machined surface demonstrate that the samples with the lowest feed rate perform better in terms of surface roughness. Surface roughness is also influenced by the wt% of alumina, which is followed by spindle speed when spinning the produced samples.
