    摘要:

    碳化硅颗粒增强铝基复合材料以其优异的力学性能在航空、航天、电子、汽车等领域发挥着重要作用。为了改善其切削性能,使用液氮喷淋实验装置对其进行铣削实验,通过研究切削力、表面完整性和切屑形貌,探索常温和低温条件下使用TiAlN涂层和TiAlSiN涂层铣刀的加工质量。结果表明,在低温条件下铣削时,两种刀具的切削力增加,铣削后表面铝基体的开裂及剥落等缺陷均显著改善,已加工表面损伤减小且粗糙度降低。低温铣削能获得更好的表面质量。此外,在常温与低温条件下TiAlSiN涂层比TiAlN涂层铣刀的切削力小,低温条件下TiAlSiN涂层铣刀表面完整性和切屑形貌优于TiAlN涂层铣刀。

    Abstract:

    Silicon carbide particle reinforced aluminum matrix composites play an important role in aviation, aerospace, electronics, automobile, and other fields due to its excellent mechanical properties. In order to improve its cutting performance, the liquid nitrogen spray experimental device was used to carry out milling experiments. The cutting force, surface integrity, and chip morphology were studied to explore the machining quality of TiAlN coating and TiAlSiN coating milling cutter under normal and low temperature conditions. The results show that when milling at low temperature, the cutting force of the two tools increases, and the surface defects such as aluminum matrix cracking and spalling are significantly improved, and the machined surface damage and roughness are reduced. Low temperature milling can obtain better surface quality. In addition, the cutting force of TiAlSiN coated milling cutters is lower than that of TiAlN coated milling cutters under normal temperature and low temperature. The surface integrity and chip morphology of TiAlSiN coated milling cutters are better than those of TiAlN coated milling cutters under low temperature conditions.
