摘　　要：CAD与 CAE、CAM脱节是目前水泵行业计算机辅助设计与制造中存在的一个突出问题。作者从现有的水力设计 CAD软件出发 ,利用开发的数据预处理程序 ,实现从型值点到轴面截线的反算。结合 Pro/E软件 ,较好地实现了叶轮叶片的实体造型 。This paper presents a data preprocessing program based on the B spline algorithm to achieve the reverse calculation from special points to axis planes transversal starting from the result of hydraulic design software in existence. After obtained the surfaces of pressure side and suction side of the blade, the entity modeling of impeller blades is achieved quickly and successfully with the help of the 3D software Pro/E. This work will be significant for further studying in calculating the flow through impellers and numerical controlled manufacture of the blade dies.
