Application of Taguchi Method for Optimization of Process Parameters of Aluminum Alloy A-356

Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. The turning process requires a turning machine or lathe, work piece, fixture, and cutting tool. The material selected for this experiment is A-356.In our work we have taken three Parameters (Feed Rate, Spindle Speed and Depth of Cut) to Optimize the Aluminum Work piece. S/N ratio and ANOVA analysis were also performed to obtain significant factors influencing Surface Roughness. L9 orthogonal array is employed by considering three factors speed, feed and depth of cut. For each factor three different levels are selected. Signal to noise ratio (S/N) and analysis of variance were employed to find the maximum material removal rate (MRR). The experimental results showed that that the optimal combination of parameters for material removal rate are at spindle speed of 600 rpm, feed rate of 2.2mm/rev, depth of cut 2.0 mm. Optimum results are finally verified with the help of confirmation experiment.
