Whirlwind milling is gaining extensive application for processing a large screw. Due to its specific forming principle, the profile of residual stresses and the deformation behavior would been given significant emphasis. Under conditions of large cutting depth (0.06–0.12 mm), the effect of cutting parameters on three characteristic parameters of the residual stress, such as surface residual stress, maximum residual stress and residual stress extreme value, was always different from that under small cutting depth (6–10 μm). Comparing to the right arc of the screw, the plastic deformation in the left arc is more obvious and far-reaching. The most extensive deformation region caused by WM cutting force was found for the topmost surface. As cutting speed increased, the nanohardness variation reflected the decreasing plastic deformation. Therefore, the research on physical change by WM is instructive for extending the fatigue life of the screw.

旋风铣削在加工大型螺杆方面获得了广泛的应用。由于其特定的成形原理，残余应力的分布和变形行为将受到极大的重视。在大切削深度（0.06-0.12 mm）的条件下，切削参数对残余应力三个特征参数的影响（例如表面残余应力，最大残余应力和残余应力极值）始终与小切削条件下的不同。深度（6–10μm）。与螺钉的右圆弧相比，左圆弧中的塑性变形更为明显且影响深远。在最表面发现了由WM切削力引起的最大变形区域。随着切削速度的增加，纳米硬度的变化反映了塑性变形的降低。因此，
