In this paper,the two-edged double point angle drill,three-edged double point angle drill and arc-shaped drill were used to drill UD-CFRP under different cutting parameters.The hole entry and exit quality (entrance damage,burr and exit delamination) were analyzed.And the burrs exist angle (α) was used to measure the number of burrs.The experimental results show that the angle α decreases first and then increases with the increase of the feed rate.Taking into account the quality of the entry and exit (burr and delamination factor), the three-edged double point angle drill is most suitable for drilling CFRP.
