摘要: 铝基碳化硅具有高耐磨性、低重量、高强度、高刚度、低膨胀系数、高导热等先进力学性能，广泛应用于汽车、铁路、航空航天等行业。该材料的应用主要限制是加工困难，这导致了低产量和高加工成本。本研究旨在探讨精密铣削加工中金属复合材料的最佳铣削参数。利用正交试验方法，选取主轴转速、进给速度和切削深度为自变量，通过在德玛吉DMC 650 V立式加工中心开展铝基碳化硅铣削试验，得到相应的试验数据，通过因素水平分析得到主轴转速、进给速度和切削深度对铣削力的影响程度，结果表明影响铣削力大小的顺序依次为：切削深度、进给速度和主轴转速，拟合了铣削力方程，采用NSGA_II多目标优化算法，计算得在切削深度为0.1 mm，进给速度为50 mm/min，主轴转速为1500 r/min时铣削质量最好。
Abstract: Aluminum-based silicon carbide has high wear resistance, low weight, high strength, high stiffness, low expansion coefficient, high thermal conductivity and other advanced mechanical properties. It is widely used in automobile, railway, aerospace and other industries. The main limitation of the application of this material is the difficulty of processing, which leads to low yield and high pro-cessing cost. This study aims to explore the optimal milling parameters of metal composites in pre-cision milling. The orthogonal test method was used to select the spindle speed, feed speed and cut-ting depth as independent variables. The aluminum-based silicon carbide milling test was carried out in the DMC 650 V vertical machining center of Demaggie, and the corresponding test data were obtained. The influence of spindle speed, feed speed and cutting depth on the milling force was ob-tained by factor level analysis. The results show that the order of influence on the milling force is: cutting depth, feed speed and spindle speed. The milling force equation was fitted. The NSGA_II multi- objective optimization algorithm was used to calculate the cutting depth of 0.1 mm and the feed speed of 50 mm/min. The milling quality is the best when the spindle speed is 1500 r/min.
