摘　　要：利用B J-042(A)型并联机床,通过多因素回归正交实验,建立了2A12铝合金材料关于切削速度v、每齿进给fz、径向切深ae、轴向切深ap四个切削参数的铣削力经验公式,并进行了单因素试验验证和时域仿真。对其应用条件进行了讨论,为进一步研究铝合金加工变形及振动提供了可靠的边界条件。A chatter displacement model of 2Al2 Al-alloy was built via the multi-element orthogonal regression experiment, aria the milling force empirical equation was established with respect to four cutting parameters of v, fz, ae, ap based on the BJ-042 （A） parallel machine tool. To verify the accuracy of the empirical equation, the single-element tests and the essential discussions and time- domain simulation were done. All these work presents the reliable boundary conditions to the further studies on the deformation and chatter of milling of aluminum alloy.
