Abstract
Biomachining is an innovative metal machining process in which metal is machined using the metabolic activity of a microbial culture instead of the hard metal cutting tool used in the conventional machining process. Nowadays, aluminum alloy has gained importance especially for its wide applicability in the construction field. There are many environmental issues involved in alloy machining which have a negative impact on surrounding, for instance, extensive use of cutting fluids. As a mitigation measure, biomachining can easily overcome above-cited issues currently faced by machining. So this study deals with biomachining of aluminum alloy 46500 using Acidithiobacillus ferrooxidans to remove metal from the workpiece. Taguchi-based design of experiments has been used to determine the effect of operating parameters such as shaking rate, pH, time and cell concentration on functioning indicators such as specific material removal rate (SMRR) and percentage change in surface roughness (%∆SR). The optimization of operating parameters is done utilizing the multi-objective genetic algorithm toolbox in MATLAB. The optimized results of the study indicate the SMRR value of 0.257 mg/h cm2 and % ∆SR of 41.37.
