镍基合金英科乃尔718是一种难加工材料，高速铣削技术的发展为英科乃尔718零件的加工提供了有效的方法。由于加工参数在Inconel 718零件的高速铣削中起着至关重要的作用，因此对加工参数的优化进行了大量的研究，并通过对Inconel 718的侧铣或槽铣试验得到了不同试验条件下的最佳加工参数。然而，高速铣削Inconel 718曲面的加工参数优化却很少涉及。曲面几何特征的变化导致切削力的剧烈波动和机床的振动，不仅对表面加工质量和刀具寿命造成严重影响，而且对高速铣削的效率也有很大影响。在具有曲面的Inconel 718零件的加工过程中，高速铣削时切削力的变化应尽量平滑。本研究基于切削力对高速铣削Inconel 718曲面的加工参数优化进行了实验研究。分析了切削力与主轴转速的关系，重点研究了加工参数的优化问题。实验结果表明：切削力与曲面的几何特征有关，主轴转速在4000 ~ 4500 rpm范围内变化时，切削力相对较小，切削力的变化更为平滑，每齿进给量对切削力的影响较小，切削深度应较小，以减小切削力的波动。研究结果可用于提高因科乃尔718曲面零件的加工质量，丰富因科乃尔718零件的加工制造理论。
Nickel-based alloy Inconel 718 is a kind of difficult-to-machine material, and the development of high-speed milling technology provides an effective machining method for the Inconel 718 parts. As the machining parameters play a crucial role in the high-speed milling of Inconel 718 parts, a lot of researches on the optimization of machining parameters have been conducted, and the optimum machining parameters under different test conditions have been obtained according to the experiments of flank milling or slot milling of Inconel 718. However, the machining parameter optimization in high-speed milling of Inconel 718 curved surface is seldom involved. The variation of the geometric features of the curved surface results in the sharp fluctuation of the cutting force as well as the vibration of the machine tool, which not only makes a severe impact on the surface machining quality and the tool life but also greatly affects the efficiency of the high-speed milling. In the machining process of the Inconel 718 parts with curved surface, the change of cutting force in high-speed milling should be smooth as far as possible. In this study, the experimental study is carried out on machining parameter optimization in high-speed milling of Inconel 718 curved surface based on the cutting force. The relationship between the cutting force and the spindle speed is analyzed, and in particular, the machining parameter optimization is investigated. The experiment results indicate that the cutting force relates to the geometric feature of curved surface, the cutting force is relatively smaller and the change of cutting force is smoother when the spindle speed changes from 4,000 to 4,500 rpm, the effect of the feed per tooth on the cutting force is little, and the cutting depth should be small to lessen the fluctuation of the cutting force. The research results can be considered to improve the machining quality of Inconel 718 parts with curved surface and will enrich the processing and manufacturing theory for the Inconel 718 parts.
