Based on this, a new tool was designed to reduce the defects in CFRP processing. An experimental comparison is conducted between the new bionic tool and the conventional dovetail and fine-toothed tool. The results show that the bionic new tool has smaller axial force and delamination factor, and the defect formation rate is slowed down under the bionic new tool. The bionic tool significantly inhibits the defect formation and improves the hole making quality of CFRP. But the drilling temperature of the new bionic tool is higher than that of the dovetail - fine tooth tool. Additionally, the comparison test of the new bionic tools with diameters of 12mm and 6mm found that the closer the tool tooth structure is to the true size of the bamboo rats lower front teeth, the better the processing effect of CFRP.
