摘　　要：针对某环形薄壁零件在加工过程中的零件局部变形过大的问题,提出了改进粒子群算法的环形薄壁零件铣削参数优化方法。采用有限元软件,对局部变形大的区域进行仿真,得到仿真出的铣削力;通过Design-Expert13中正交实验响应曲面法建立加工参数与铣削力之间的目标函数,采用改进的粒子群算法对目标函数进行优化,最后通过对优化后的加工参数与经验加工参数进行实验对比。结果表明:采用改进粒子群算法的环形薄壁零件铣削参数优化的方法,可使零件局部变形大的区域的铣削力减小24.9%,有效降低了环形薄壁零件的变形量,为技术人员在选择该环形薄壁铣削参数时,提供了新的参考方案。An improved particle swarm optimization method for milling parameters of ring thin-walled parts was proposed to address the issue of excessive local deformation of a ring thin-walled part during machining.By using finite element software,the simulation of the region with large local deformation is carried out to obtain the simulated milling force,and the objective function between the machining parameters and the milling force is established using Design-Expert13's orthogonal experimental response surface method.The improved particle swarm optimization algorithm is then used to optimize the objective function.Finally,the results demonstrate that the method of milling parameters optimization of annular thin-walled parts with an improved particle swarm algorithm can reduce the milling force in this region of the part with large local deformation by 24.9%,effectively reducing the deformation of annular thin-walled parts,and providing a new reference scheme for technicians in selecting milling parameters for annular thin-walled parts.
