Abstract High-speed ultrasonic vibration cutting (HUVC) has been proved highly effective for the finishing of titanium alloy at high cutting speed. In this study, HUVC is used for the first time to improve the machinability of Inconel 718 during the process of finish machining with coated carbide tools. First, the intermittent cutting of HUVC is analysed. Then, the feasibility of HUVC for finish machining Inconel 718 is verified experimentally in comparison with conventional cutting (CC). The results showed that, compared with CC, HUVC extends the tool life by up to 250% through significantly reduced tool wear and decreases the cutting force by up to 32.59% and cutting temperature by ~20%. Moreover, HUVC can obtain better surface roughness during a successive cutting process.

带涂层硬质合金刀具的高速超声振动切削提高 Inconel 718 切削性能的性能评价

摘要 高速超声振动切削（HUVC）已被证明在高速切削钛合金时非常有效。本研究首次在涂层硬质合金刀具精加工过程中使用 HUVC 来提高 Inconel 718 的可加工性。首先，对HUVC的断续切割进行了分析。然后，与传统切削 (CC) 相比，通过实验验证了 HUVC 对 Inconel 718 进行精加工的可行性。结果表明，与 CC 相比，HUVC 通过显着减少刀具磨损将刀具寿命延长了 250%，并将切削力降低了 32.59%，切削温度降低了约 20%。此外，HUVC 可以在连续切割过程中获得更好的表面粗糙度。
