The concept of "Micro Factory" and miniaturization of production machines for saving energy and space is recently the subject of many environmental-conscious research works. In this study a 3-axis desktop electro-discharge drilling machine is introduced that uses a personal computer as its controller. Therefore the downsizing includes both the machine tool and its controller unit. The software can control feed speed and work-electrode gap. Experiments were performed on stainless steel using a flush-through copper electrode. In order to investigate the effect of control methods, different conditions were examined. The results indicate that for higher material removal rate, current controlling method is preferred compared to the voltage-controlled process.
