Ti-5553（Ti-5Al-5V-5Mo-3Cr-0.5Fe）合金具有优异的综合力学性能，正逐步替代TC4（Ti-6Al-4V）钛合金成为高强度航空用工件的制备材料。然而，由于Ti-5553合金机械加工效率低，一定程度上制约了其在航空领域的大规模应用。为此，对Ti-5553合金与TC4钛合金的车削加工性能参数进行了探索，发现在相同的切削速度下， Ti-5553合金的主切削力和吃刀抗力均高于TC4钛合金，且最高切削速度仅为50 m/min。此外，两种合金在切削过程中均会与车刀发生扩散反应，而Ti-5553合金对刀具的磨损更为严重。相信本研究将为后期优化Ti-5553合金的车削加工参数、提高其加工效率提供有利的实验数据支持。

Ti-5553(Ti-5Al-5V-5Mo-3Cr-0.5Fe) alloy has excellent comprehensive mechanical properties , and it is substituting for TC4 ( Ti-6Al-4V) titanium alloy to produce the high strength workpieces in aviation .However, due to the lower machining efficiency of Ti-5553 alloy, the use in the industry of aviation is restricted .So the parameters in cutting process of Ti-5553 alloy and TC4 titanium alloy were achieved by experiment .The results show that the cutting force of Ti-5553 alloy is higher than TC4 titanium alloy under the cutting speed , and the maximum allowed speed is only 50 m/min for Ti-5553 alloy .Besides , the diffusion reactions both have occurred during the cutting processes . This research will give an experimental data support to optimize the cutting processing parameters and increase the machining efficiency .
