Abstract

SiC particle-reinforced Al metal matrix (SiCp/Al) composites are more and more widely used in the aerospace field due to their excellent properties, and the realization of high-quality drilling of SiCp/Al composites has an important impact on improving the performance of parts. In this paper, ultrasonic elliptical vibration-assisted helical milling (UEVHM) is applied to the machining of SiCp/Al composites. Firstly, the kinematic analysis of UEVHM is carried out, and then the cutting force model is established, which takes into account the interaction between particles and the cutting edge, and calculates the crushing force, pressing force, and debonding force of the particles. Finally, the UEVHM tests are conducted to verify the accuracy of the model and to analyze the influence of process parameters on the cutting force. It was found that the radial and axial forces decreased by 34% and 39%, respectively, when the spindle speed was increased from 2000 r/min to 10,000 r/min; the radial and axial forces increased by 200% and 172%, respectively, when the pitch increased from 0.1 mm to 0.4 mm; and the radial and axial forces increased by 29% and 69%, respectively, when the rotational speed increased from 30 r/min to 70 r/min. The maximum error between the cutting force model and the experimental values is 19.06%, which has a good accuracy. The research content of this paper can provide some guidance for the high-quality hole-making of SiCp/Al composites.

超声波椭圆振动辅助螺旋铣削 SiCp/Al 复合材料的切削力模型

碳化硅颗粒增强铝金属基（SiCp/Al）复合材料因其优异的性能在航空航天领域得到越来越广泛的应用，而实现 SiCp/Al 复合材料的高质量钻孔加工对提高零件性能具有重要影响。本文将超声波椭圆振动辅助螺旋铣（UEVHM）应用于 SiCp/Al 复合材料的加工。首先对 UEVHM 进行了运动学分析，然后建立了切削力模型，该模型考虑了颗粒与切削刃之间的相互作用，并计算了颗粒的破碎力、压紧力和脱开力。最后，通过 UEVHM 试验验证模型的准确性，并分析工艺参数对切削力的影响。结果发现，当主轴转速从 2000 r/min 提高到 10,000 r/min 时，径向力和轴向力分别降低了 34% 和 39%；当螺距从 0.1 mm 增加到 0.4 mm 时，径向力和轴向力分别增加了 200% 和 172%；当转速从 30 r/min 提高到 70 r/min 时，径向力和轴向力分别增加了 29% 和 69%。切削力模型与实验值的最大误差为 19.06%，精度较好。本文的研究内容可为 SiCp/Al 复合材料的高质量孔加工提供一定的指导。

期刊介绍： Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
