摘　　要：铣削速度和铣削深度显著影响铣削共形件的残余应力,为了获得航空共形薄壁结构件用5A06铝合金材料高速铣削过程中铣削参数对残余应力的影响,因此进行了基于Advantage的铝合金5A06高速铣削三维仿真研究。基于J-C本构方程模拟工件的应力应变关系,研究了铣削速度和铣削深度对表面残余应力的影响规律,为进一步有效控制共形件结构变形提供了新的研究方法,研究共形件表面残余应力的规律对于铣削加工参数的选取具有一定的参考价值。In order to obtain the influence of the milling parameters on the residual stress during the high-speed milling of 5A06 aluminum alloy material for aeronautical conformal thin-walled structural parts,the aluminum alloy5A06Research on3D Simulation of High Speed Milling.Based on the constitutive equations of J-C simulating the stress-strain relationship of workpieces,the influences of milling speed and milling depth on the residual stress of the surface are studied,and a new research method is provided to further effectively control the deformation of conformal structures.The law of residual stress has certain reference value for the selection of milling parameters.
