摘要：提出了四坐标侧铣方法加工叶轮等不可展直纹面理论，并按相对接触条件确定了圆柱刀具与工件的相对位置。相对于端铣加工，该方法大幅度减小了切削余量。最后，通过数控实验验证了该方法的可行性，并结合了径流式叶轮机械轴—径型叶轮抛物面叶片的成型设计计算方法，使设计计算和加工计算更方便，加工效率更高。

Abstract: A numerical control (NC) method of 4axis side milling to generate the ruled surface such as the vane wheel was presented. The relative position between the tool and the work was determined by the contact condition. Compared to the end milling, the cutting allowance was deceased dramatically. The forming design and calculation method of curved impeller blade in axle of radial turbomachinery was connected with the research. The result shows that the calculation of design and machining is more convenient, the machining efficiency is higher than that of before.
