摘　　要：旋风铣削能有效地提高轴类零件的加工效率,也能明显地改善零件加工的表面质量。考虑到丝杆加工振动对螺距误差有着明显影响,结合旋风铣削特殊的约束方式,建立了工件受轴向切削力激励时的弯曲振动模型,分析了不同工艺参数下工件的轴向偏移量均值和总值变化规律,为提高轴类零件加工的几何精度提供了重要的理论依据。The Whirlwind Milling(WM)could improve the processing efficiency and surface quality of shaft parts effectively.Considering the significant influence of machining vibration on screw lead error,a vibration model was established with WM special constraint way.For the screw,the axial offset in the mean and total value were analyzed under different process parameters,which is of great theoretical significance and practical value for reducing the machining lead error.
