Abstract

Bio-micromachining is upcoming future unconventional manufacturing  process. It has many benefits over other conventional as well as non-conventional process, some of them are no heat-affected zone, no recast layer, no formation of the white layer, and many others. In the present paper, bio-micromachining on copper has been demonstrated. Fabrication of microchannel, as well as optimisation of the process, is done by using central composite run design (CCRD) in combination with response surface methodology (RSM). ANOVA analysis shows that the machining time is the main influencing parameter followed by inoculum size. The maximum material removal obtained was 0.571 grams, when machining time was 32 h and inoculum size was 7.5% (v/v). It is suggested to use the inoculum age of microorganism after 5 days of culture and best before 12 days, in order to get the maximum amount of material removal.
