【 摘 要 】

The machining process is a part of the production technology used in almost every manufacturer of industrial products. The world of the industry continues to grow along with technology, emerging machining technology that can produce miniaturization products on of that is a micro-drilling process. This research observed the dimension accuracy and burr development on micro drilling process on Aluminium. The accuracy of the hole dimension and burr development on top and bottom were observed on three different cutting speed. The thickness of aluminum as the workpiece is 0.5mm and drill with a diameter of tungsten carbide drill bit 0.3mm. The results show at the cutting speed of 13,2 m/min, the largest hole diameter was found 0.3117 mm, while the smallest hole diameter is 0.3039 mm measured at a cutting speed of 18.8 m / min. For the top burr height found that the largest number is 0.19 mm and the smallest number at 0.07 mm. While the bottom burr height has the highest value of 0.39 and the lowest at 0.12 mm, it can be concluded that the deviation of hole dimension size and burr height is inversely proportional to cutting speed.
