摘　　要：利用7075-T651铝合金材料为试验对象,采用四因素四水平的回归正交方法,分析研究加工铝合金材料时的铣削速度、铣削深度、铣削宽度和每齿进给量对铣削力的影响规律;并通过MATLAB编程回归分析得到铣削力的经验公式。研究结果表明,建立的7075铝合金铣削力模型真实可靠,对铣削过程中影响最大的是铣削深度,其次是铣削宽度,进给量的影响较小;铣削力随着速度的增大而降低。模型可为航空铝合金铣削加工的变形提供可靠的边界条件。This paper uses 7075 -T651 aluminum alloy materials for experimental research object and uses four fac- tors and four levels orthogonal method of regression analysis. When process the Aluminum alloy material, this paper studies milling speed,width of milling depth,milling width and feed engagement for the influence law of milling forces and obtain the experience formula of the milling force by using MATLAB regression analysis. The results show that ：7075 Aluminum al- loy milling force model is reliable and has influence on the milling process, milling depth is the biggest, the width in the second, less influence of feed. But the milling force decreases with the increase of speed. These models will provide reliable boundary conditions for the deformation of aerospace Aluminum alloy milling.
