Comparison Study on Machining Property of Drilling Tools for CFRP/Titanium Alloy Laminated Structures

  • 摘要: 钛合金与碳纤维增强复合材料(Carbon-fiber reinforced plastics,CFRP)均广泛应用于航空航天领域。钛合金/复合材料构成的叠层构件对钻孔刀具提出了更高的要求。试验采用两种不同“变顶角”结构的钻头进行了钛合金/CFRP叠层构件钻孔实验。并对比分析了两种刀具加工孔的表面质量和切削力。结果发现:顶角由小变大的钻头轴向力较大,出口质量较差,但转矩小,孔径精度高,孔壁质量好;而顶角由大变小的钻头转矩较大,孔壁质量较差,但轴向力小,能有效抑制出口毛刺和撕裂,减小CFRP层孔的圆柱度误差。因而在加工以复合材料为出口的叠层构件时,顶角由大变小的钻头更具有优势。
