摘要
碳纤维增强树脂基复合材料(CFRP)与钛合金组成的叠层构件被广泛应用于航空航天领域,CFRP/Ti叠层材料的制孔加工一直是航空领域的热门话题。在使用机器人对飞机上的大型CFRP/Ti叠层构件进行制孔加工时,应在加工过程中尽量保持较小的轴向力。因此,为了研究钻头几何参数对CFRP/Ti叠层材料加工轴向力的影响,采用不同几何参数的无涂层硬质合金麻花钻对CFRP/Ti叠层材料进行钻削试验。结果表明,对CFRP/Ti叠层材料加工轴向力的影响顺序由大到小依次为横刃>顶角>螺旋角;当钻头的几何参数为顶角119°,螺旋角19°,横刃长0.3mm时,加工轴向力最小,制孔质量更好。
Carbon fiber reinforced resin matrix composites(CFRP)and titanium alloy laminates are widely used in the aerospace field,and the hole making process of CFRP/Ti laminates always has been a hot topic in the aerospace field.When robot is used to drill holes in large CFRP/Ti laminates on aircraft,the axial force should be kept small as much as possible.Therefore,in order to study the influence of drill geometry parameters on the axial force of CFRP/Ti laminates,uncoated cemented carbide twist drill with different geometry parameters are used to drill CFRP/Ti laminates.The results show that the order of influence on the axial force of CFRP/Ti lamination materials is transverse edge>apex angle>spiral angle.When the geometric parameters of the bit are 119°apex angle,19°helix angle and 0.3mm transverse edge length,the machining axial force is minimum and the hole making quality is better.
