Abstract
Micro-manufacturing is one of the growing technologies of near future. Non-traditional machining processes have been found to be beneficial for micro manufacturing using low density of energy for metal removal. To overcome environment related problems of chemical machining, biomachining has been developed over several years by making use of the metabolic activity of microorganisms. Besides many advantages of biomachining such as environmental friendly, low consumption of energy and no heat affected zone generation during machining; one of the common short comings reported by early researchers is a low metal removal rate. In this study, firstly effect of process parameters variation on SMRR and MRR is investigated. Secondly taguchi design of experiment (DOE) approach is used to establish rank of most influential process parameters for maximum metal removal rate. Finally optimal values of selected parameters are predicted and verified. It is observed that process parameters can be optimized to obtain a higher metal removal rate. Micro features are fabricated using optimum process parameters to show the impact of fine tuning on the metal removal rate.
