摘　　要：文章针对汽轮机叶片曲面的加工特点,建立了铣削力模型,并从瞬时切削厚度的角度分析了数控工艺参数对铣削力模型的影响。在金属切削有限元模拟的基础上,运用Matlab和Abaqus软件结合四因素四水平正交模拟试验法验证了铣削力模型。并运用汽轮机叶片铣削加工实验进一步验证了铣削力模型和金属切削有限元模拟模型的有效性。Based on the characteristics of the turbine blade surface processing,milling force model is established. From the perspective of the instantaneous cutting thickness,the relationship between the numerical process parameters and the milling force model is analyzed. On the basis of finite element simulation of metal cutting,using M atlab and Abaqus combined with four factors and four levels orthogonal simulation test method,the effectiveness of the milling force model has been verified. Turbine blade machining experiment has been used to further verify the Validity of the milling force model and the metal cutting finite element simulation model.
