Micro drilling is a very important machining method to produce precise parts or small molds. General macro-program for drilling is a non-efficient method because of many movements to safety height. In this research new macro-program was suggested to raise machining-efficiency. New micro-drilling method caused the much reduction of machining time and the same tool life.
