面向CFRP制孔毛刺抑制的钻头副刃改型方法
Modification Strategy of Drill Structure for Hole-exit Debur in Drilling of CFRP
摘要
Abstract
Firstly,the bearing condition of the fibers around hole-exit in drilling of carbon fiber-reinforced polymer (CFRP) was analyzed.Based on the present analysis,the burr formation mechanism is presented and the quantification method for hole-exit burr was given.Secondly,the conception of " forward" and " reverse" cutting was defined.Then the minor cutting edge was modified according to the "reverse" cutting.Thirdly,the angles of the modification cutting edge were determined with respect to the dynamic drilling angle and the burr thickness.The grinding method was also presented.Lastly,the experiments were conducted to verify the validation of the modification drill bit in minimizing hole-exit burr.关键词
