摘　　要：基于特征制定整体叶轮数控加工工艺,同时兼顾叶轮的工作要求和加工刚度,利用UGNX3.0提供的Interpolate方式规划流道特征的开粗加工和精加工轨迹,Swarf方式规划叶片特征的侧铣加工轨迹。经过仿真验证加工轨迹的合理性,最后使用配有HNC-22M数控系统的五轴加工中心VMC-1100成功加工了整体叶轮。The machining process of integrated impeller is prepared basing on the geometry feature. Considering the working performance and machining rigidity, the rough machining and finish machining toolpath of hub are generated in interpolate manner and the flank milling toolpath of vane is created in Swarf manner. After simulating the machining toolpath, an integrated impeller is machined by 5 - axis machining center VMC - 1100 which equipped with HNC- 22M.
