Series experiments were conducted to analysis the effect of processing parameter on formed burr, particularly the axial feed, had a great effect on volume burr. Experiments finds that, the volume of burr at hole entrant is less than that at hole exit, and the burr volume has great effect on workpiece quality and product cost, the burr height formed easily decreases because great attention from scholars and engineers has been paid to, while the burr width size despised naturally plays a great influence on product quality and machining cost. Finally, The new de-burring tool are designed and applied in experiment, the decrease in burr width is obviously found, so the removal of burrs becomes much little than that gotten in traditional tool. The result indicates a promising future of de-burring in practical application. KEYWORDS Drilling, Burr, De-Burr, Hole Exit, Hole Entrance.
