OPTIMIZATION OF CUTTING PARAMETERS OF AL-ZRO2- SICP AND GRAPHITE HYBRID METAL MATRIX COMPOSITES

Abstract

Paperwork deals with fabrication, cutting parameter optimization as well as the effect of Zirconia on surface roughness and cutting force of hybrid-composites such as Al/7%SiC/1.75%Gr/2.75%ZrO2, Al/7%SiC/1.75%Gr/4.5%ZrO2, and Al/7%SiC/1.75%Gr/6%ZrO2. Considering Depth of cut (d.o.c), Feed and vol.% of ZrO2 as input parameters. Taguchi experimental design of L27, S/N ratio and ANOVA were conducted. Optimal parameters for cutting force were observed at feed 0.0599 mm/rev, d.o.c 1mm with 6% ZrO2 and for Surface roughness at feed rate 0.0143 mm/rev, d.o.c 0.5 mm with Zirconia 2.75 %. Relation among the parameters were presented by regression-equation. 3D and contourplots were used to analyse effect of two factors on responses.
