碳纤维增强塑料（CFRP）和钛基材料具有优异的性能，使其在航空工业中具有吸引力。然而，这两种类型的材料都被认为是难以加工的材料。超声波辅助钻孔（UAD）是一种非传统的混合加工工艺，它结合了传统钻孔和振动加工技术的特点，可显着提高先进难加工材料的切削性能。在这项工作中，超声波辅助钻孔 (UAD) 与使用 CFRP 和 Ti6Al4V 作为工件材料的传统钻孔 (CD) 进行了比较，以便了解这种先进混合工艺在生产零件质量方面的优势，并研究 CD 和 UAD 中钻孔参数的影响。获得的结果证明，UAD 在所有测试条件下都具有更低的切削力、更低的加工温度、更少的分层和更好的表面光洁度，因此它是制造需要钻孔的 CFRP 和 Ti6Al4V 部件的良好替代方案。
Carbon fibre reinforced plastics (CFRP) and titanium based materials have excellent properties that make them attractive in the aeronautic industry. Nevertheless both types of materials are considered as difficult-to-machine materials. Ultrasonically assisted drilling (UAD) is a non-traditional hybrid machining process, which combines features of conventional drilling and vibratory machining techniques to obtain remarkable improvements in machinability of advanced, difficult-to-machine materials. In this work ultrasonically assisted drilling (UAD) has been compared to conventional drilling (CD) using both CFRP and Ti6Al4V as workpiece materials, in order to see the benefits of this advanced hybrid process with regard to the quality of the produced parts and also to study the effect of drilling parameters both in CD and in UAD. The results obtained prove that UAD entails lower cutting forces, lower process temperatures, less delamination and better surface finishing at all the conditions tested, so it is a good alternative for manufacturing of CFRP and Ti6Al4V components where drilling is necessary.
