In this study, machinability properties of aluminium matrix boron carbide (B₄C) and carbon nanofiber (CNF) reinforced hybrid composite material produced by powder metallurgy in drilling were investigated. In the study, the samples produced with hot pressing technique having 6 different volume rates were used. The drilling operations were performed using drills with 3 point angles (90°–118°–135°) at 30–45-67.5 m/min cutting speed and 0.1–0.15–0.225 mm/rev feed rate. As a result of the experiments, the thrust force, moment, and surface roughness were measured and the delamination factor forming at hole exits was calculated. In addition, the effect of reinforcement rate on the machinability was also investigated. In all drill types, it was determined that as the feed rate increased, the thrust force increased and as the reinforcement rate increased, moment values also increased. Surface roughness values increased with the increased feed rate but decreased as the cutting speed increased. As the drill point angle increased, the surface roughness value decreased but the hole exit damage increased.

在这项研究中，铝基碳化硼（B ₄C）和粉末冶金钻探生产的碳纳米纤维（CNF）增强杂化复合材料进行了研究。在研究中，使用通过热压技术生产的具有6种不同体积比的样品。使用具有3个尖角（90°– 118°– 135°）的钻头以30–45–67.5 m / min的切削速度和0.1–0.15–0.225 mm / rev的进给速度进行钻孔操作。实验的结果是，测量了推力，力矩和表面粗糙度，并计算了在孔出口处形成的分层因子。另外，还研究了补强率对切削性的影响。在所有类型的钻机中，可以确定，随着进给速度的增加，推力增加，而随着增强速度的增加，力矩值也增加。表面粗糙度值随着进给速度的增加而增加，但随着切削速度的增加而降低。随着钻尖角度的增加，表面粗糙度值减小，但孔出口损坏增加。
