“…They reported a U-shaped profile for a rectangular groove with width and depth that increase proportionally to the machining time. Recently, Jadhav et al 7 (2013) reported the possibility of biomachining with only ferric ions by removing bacteria from a culture solution and Eskandarian et al 8 reported the enzymatic biomachining using glucose oxidase. All these studies reported the capabilities of biomachining for micro fabrication.…”

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.

Enzymes are powerful tool that help to maintain an unpolluted environment through their use in waste management. Enzymatic bioremediation is potentially a rapid method for removal of pollutants. Therefore, the present study has been carried out to investigate the possibility of bioleaching of metals from printed circuit board (PCB) powder by enzymatic bio-Fenton process. To do this glucose oxidase enzyme was used for in situ production of hydrogen peroxide (H 2 O 2 ). The H 2 O 2 was further used in Fenton's reaction for conversion of Fe(II) into Fe(III). Effects of various parameters such as incubation time, temperature, pH, and shaking speed on conversion of Fe(II) into Fe(III) were assessed. This enzymatic bio-Fenton process was further applied for bioleaching of metals. The results showed that metal recovery increased with an increase in initial Fe(II) concentration. Maximum recovery of metals was achieved at 250 mM initial Fe(II) concentration. The metal recovery decreased with an increase in concentration of PCB powder. The present research put forth a novel method for bioleaching of metals.

Abstract-Micro-manufacturing is one of the fastest growing technologies and non-traditional machining processes have been found to be beneficial for micro manufacturing using low density of energy for metal removal. In biomachining the metabolic function of the bacterium is utilized, no physical or chemical energy needs to be focused at the machining point, thereby avoiding the possibility of generating a damaged layer or a heat-affected zone in the machined surface. In biomachining, microorganisms are used to create the desired part(s) of the metals to the required dimensions. In this study an attempt has been made to understand the basics of "Biomachining" along with the factors effecting the output performance characteristics.
