这项工作的重点是研究切削刀具的几何形状和材料对钻削玻璃纤维增强环氧复合材料时产生的推力和分层的影响。测试了四个具有不同几何形状和组成的钻头。此外，还研究了切削参数的影响。总体而言，EDP27199钻头的推力值较低，而A1167A钻头（带三个切削刃）的推力值最高。与其他报告相反，没有观察到推力和分层之间的直接关系，即负责最高推力的钻头也负责第二小的分层面积。最后，在所测试的切削范围内，损伤面积随进给量的增加而显著增加，随切削速度的增加而适度增加。(c) 2007年Elsevier Ltd.出版
This work is focused on the investigation of the effect of the cutting tool geometry and material on the thrust force and delamination produced when drilling a glass fibre reinforced epoxy composite. Four drills with distinct geometries and composition were tested. Additionally, the influence of the cutting parameters was studied. Generally speaking, the results indicated that lower thrust force was observed using drill EDP27199, whereas drill A1167A (with three cutting edges) gave highest thrust force values. In contrast to other reports, a direct relationship between thrust force and delamination was not observed, i.e., the drill responsible for the highest thrust force was also responsible for the second smallest delaminated area. Finally, within the cutting range tested the damaged area increased considerably with feed rate and moderately with cutting speed. (c) 2007 Published by Elsevier Ltd.
