SiCp/Al复合材料具有优异的材料性能，是重要的轻金属基复合材料之一，广泛应用于航空航天和电子工业等领域。了解磨粒作用的机理和切削力的产生对于获得所需的孔质量和加工精度至关重要。然而，目前还没有关于SiCp/Al复合材料钻削切削力模型的研究。本文首次提出了一种基于能量的机械建模方法来预测SiCp/Al复合材料钻削时的切削力。为了描述磨粒作用所消耗的能量，提出了一种新的综合磨粒模型，该模型考虑了不同的颗粒作用机理，如破裂、脱粘和挤压。在不同颗粒体积分数和进料速率以及不同颗粒尺寸下进行了实验，验证了所提模型的准确性。结果表明，该模型能准确预测SiCp/Al复合材料钻削时的切削力，平均误差为6.55%。此外，磨粒作用所消耗的能量估计占总切割能量的8.2-13.6%。所提出的SiCp/Al复合材料模型可以推广到其他颗粒增强金属基复合材料。
SiCp/Al composite is one of the key light metal matrix composites widely used in aerospace and electronics industries due to its excellent material properties. Understanding the mechanism of abrasive particle action and the cutting force generation is crucial for achieving desired hole quality and machining accuracy. However, there is no research on cutting force modeling in drilling of SiCp/Al composites. This paper proposes an energy-based mechanistic modeling method to predict the cutting force in drilling of SiCp/Al composites for the first time. A new comprehensive abrasive particle model considering different particle action mechanisms, such as cracking, debonding, and squeezing, is presented to depict the energy consumed by abrasive particle action. Experiments with a wide range of particle volume fractions and feed rates, and different particle sizes were carried out to validate the accuracy of the proposed model. Results show that the proposed model can accurately predict the cutting force with an average error of 6.55% in drilling of SiCp/Al composites. Furthermore, the energy consumed on abrasive particle action is estimated to be 8.2–13.6% of total cutting energy. The proposed model on SiCp/Al composites can be extended to other particle reinforced metal matrix composites.
