Deburring of micro-structures is found to be a tedious job. But it is to be done during machining of micro-channels. This article describes the experiments conducted to remove top burrs in micro-channels produced by micro-milling. The correlation between burr size and feed rate is studied. The burr formation in the down-milling side always tends to be higher than that on the up-milled side. This is correlated with the so-called size effects in tool-based micro-machining. The bottom surfaces of the micro-channels are studied for surface quality. Moderate feed rate (1.25 µm/tooth) produces better surface quality and less top burrs. Micro-EDM is employed to remove the top burrs. Different energy levels were employed in a capacitance-based micro-EDM. It is found that the lesser the energy level better the deburred surface. High energy levels tend to damage the quality of the micro-channels.
