| Abstract: | Constructing freeness-curve and surface in design process of the hydro-machine vane by NURBS(non-uniform rational B-spline) was discussed in this paper. The uniform mathematic model was used to construct freeness-curve and conic-curve in CAD system designing of the hydro-machine vane. It could express the conic-curve accurately,strengthen the interactive design function of the system. It has important significance for improving the designing method of the vane and enhancing quality of the vane. |
