摘　　要：复合材料与金属组成的叠层结构已在航空航天领域广泛使用,然而在复合材料/金属叠层结构上钻削高质量的孔仍是一个挑战。本文旨在研究钻削工艺参数对GFRP/Al叠层材料钻削轴向力和制孔表面质量的影响。使用普通硬质合金麻花钻对GFRP/Al叠层材料进行“一次性”钻孔,并通过Kistler测力仪测量钻削轴向力。结果表明,最大钻削轴向力随每转进给量增加几乎线性增加,随主轴转速增加小幅降低。钻削工艺参数影响铝合金和GFRP制孔表面质量,高每转进给量会降低铝合金制孔出口毛刺,但是会增加GFRP制孔出口损伤;高主轴转速会增加铝合金制孔出口毛刺和GFRP制孔出口损伤。与每转进给量相比,主轴转速对铝合金和GFRP制孔质量影响更大。The stacks structure composed of composite materials and metals has been widely used in the aerospace field,but drilling high-quality holes on composite/metal stacks structures remains a challenge.This article aims to investigate the influence of drilling process parameters on the axial force and surface quality of GFRP/Al stacks materials during drilling.The common carbide fried dough twists drill is used to drill the GFRP/Al stacks material“once”,and the drilling axial force is measured by the Kistler dynamometer.The results show that the maximum drilling axial force increases almost linearly with the increase of feed rate per revolution,and decreases slightly with the increase of spindle speed.The drilling process parameters affect the surface quality of aluminum alloy and GFRP hole making.High feed rate per revolution will reduce the burrs at the aluminum alloy hole making outlet,but it will increase the damage at the GFRP hole making outlet;high spindle speed will increase the burrs at the aluminum alloy hole outlet and damage at the GFRP hole outlet.Compared to the feed rate per revolution,the spindle speed has a greater impact on the quality of aluminum alloy and GFRP drilling.
