Optimization of Machining Parameter on Surface Roughness in Drilling of SG 500/7 Material: A Review

Abstract

In recent days main objective of every manufacturing industries is to produce low cost and high quality products
in short time. The selection of optimal cutting parameters is a very important problem for every machining process in order
to increase the quality of machining products and reduce the machining costs. In this study, focuses on the optimization of
drilling parameters using the Taguchi technique to obtain minimum surface roughness. A number of drilling experiments will
conduct using the orthogonal array on vertical machining centre. The experiments is perform on Spheroidal Graphite material plate using three different twist drills under dry cutting conditions. The measured results are collects and analyze with
the help of the commercial software. Analysis of variance is employed to determine the most significant control factors affecting the surface roughness. The spindle speed feed rate and tool material is selected as control factors. The main and interaction effect of the input variables on the predicted responses are investigate. The predicted values and measured values are
fairly close.
