The method proposed inserts periodic, decelerated feed at infinitesimal width into continuous feed at a certain pitch (hereafter referred to as intermittently decelerated feed). An attempt was made to break chip produced from drilling by intermittently decelerated feed. It was found that the chip is broken into easily disposable smaller pieces by optimizing the interval and the rate of feed deceleration. The axial deviation of hole in intermittently decelerated feed is lower than that the continuous feed. As a result of research on round of hole with work material S 45 C, no difference in round of hole was observed in intermittently decelerated feed compared with continuous feed. The tool life of intermittently decelerated feed in drilling is longer than that of continuous feed.
