This paper presents the experimental characterization of micro drilling process under conditions of dry, compressed air and minimum quantity lubrication (MQL). A series of micro drilling experiments were conducted in the miniaturized desktop machine tool system. Micro drills with the diameter of 200 um were used in the experiments, and the workpiece was aluminum 6061. The experimental results showed that MQL reduced the adhesion of chips when compared with the case of dry micro drilling. As a result, it was observed that the magnitudes of average drilling torque and thrust force were decreased and the tool life of micro drills was extended in the case of MQL micro drilling.
