| Research Abstract |
Drilling experiments of CFRP/Ti6Al4V laminated stack board were carried out use of a TiN/AlN-coated cemented carbide drill and a TiAlCr/TiSi-coated cemented carbide drill. In the experimental conditions described herein, tool life is longer for lowered feed speed, and a TiAlCr/TiSi-coated cemented carbide drill has longer life than the other. Additionally, the cooling performance between dry process and water-mist-cooling were compared. For a number of holes less than 50, water-mist-cooling reduces tool abrasion. However, the abrasion increases suddenly for hole numbers greater than 50.
