件以圆柱螺旋铣刀周铣加工过程为研究对象，在考虑主轴偏心以及刀杆的静、动态变形等影响因素的前提下，建立一种考虑刀杆柔性的周铣加工表面创成模型。基于该模型，用相应的高效数值仿真算法，对给定稳态和非稳态两种切削条件下的铣削加工表面形貌进行仿真，并与实测加工表面进行对比，用以验证该模型的有效性
In this paper, the circumferential milling process of cylindrical spiral milling cutter is taken as the research object. Based on the consideration of the eccentricity of the spindle and the influence of the static and dynamic deformation of the cutter bar, a model of the surface milling machining surface considering the flexibility of the cutter bar is established. Based on this model, the corresponding high efficiency numerical simulation algorithm was used to simulate the surface morphology of milling under given steady state and unsteady conditions, and compared with the measured surface to verify the effectiveness of the model Sex
