- Abstract
During the research on high-quality hole drilling technology for glass fiber–reinforced polymer (GFRP), more and more researchers have discovered and focused on the coupling effect between the machining parameters on the damage at the hole exit. Most of them have verified and described this phenomenon by mathematical statistics, but there is no further analysis for its mechanism. In this paper, a set of orthogonal experiments were conducted to investigate the coupling effect between the clearance angles of outer cutting edges, the spindle speed, and the feed speed when drilling the GFRP materials with candlestick drills. Through the experimental results shown by the response surface, the influencing factors of the exit damage were divided into the pushing effect, cutting effect, and the physical properties of the material according to the special damage formation process. It was found that the reason for the coupling effect of the machining and tool parameters was that the change of these parameters would have different effect on the pushing, cutting, and physical properties of the materials at the same time. In addition, the optimal machining parameters for each candlestick drill were also given according to the experimental results.
