Machining process that use microorganism as the tool to remove metal from a work piece, also known as biomachining, is an alternative technologies in machining process since its environmental advantages. The study of characteristic of micromachining using microorganism such as Acidithiobacillus ferrooxidans is needed to explore and to improve its capability as an alternative machining process. The objective of this study is to characterize the surface roughness, the material removal rate and bacteria concentration in biomachining of cooper for 3 different machining time. Biomachining experiment and the results such as the change of surface roughness of work pieces and Material Removal Rate are presented.
