【摘要】 铝合金凭借其优异的耐腐蚀性、良好的疲劳性能以及出色的可加工性，已成为航空航天、交通运输等领域不可或缺的关键结构材料。然而，由于其本身刚度较低，且多为薄壁或薄板结构，在加工过程中受到切削力、装夹力和残余应力的耦合作用，极易发生加工变形，导致尺寸误差与形状误差。因此，深入探究铝合金加工变形机理，预测并控制加工变形对于提高加工效率与加工质量具有重要意义。综述了近年来铝合金加工过程中的变形机理与控制策略方面的研究进展，从初始残余应力、加工残余应力、切削力和装夹方式等方面系统地阐述了不同铝合金薄壁结构件加工变形的形成机制与变形控制方法，展望了未来铝合金高效、高精度加工的研究方向和发展趋势。更多还原

【Abstract】 Owing to its excellent corrosion resistance, favorable fatigue performance, and outstanding machinability, aluminum alloy has been regarded as an indispensable key structural material in fields such as aerospace and transportation. However, due to its relatively low stiffness and the prevalence of thin-walled or thin-plate structures, machining deformation is highly prone to occur under the coupled effects of cutting forces, clamping forces, and residual stresses during processing, leading to dimensional and geometric inaccuracies. Therefore, an in-depth investigation into the mechanisms of machining-induced deformation in aluminum alloys, along with the prediction and control of such deformations, is of great significance for improving machining efficiency and quality. Recent research progress on deformation mechanisms and control strategies in the machining of aluminum alloys is reviewed. The formation mechanisms of machining deformations in various thin-walled aluminum alloy structural components are systematically analyzed from the perspectives of initial residual stress,machining-induced residual stress, cutting forces, and fixturing schemes, along with corresponding deformation control methods. Finally, future research directions and development trends for achieving high-efficiency and high-precision machining of aluminum alloys are discussed.更多还原
