| Abstract: | The part of impeller sort and blade sort is the one important unit which is used in automobile,aviation and other fields. Its modeling method is the key for men to research all the time.This paper use NURBS method (non-uniform rational and Bsplens) to build model of impeller sort and blade sort, which offer the base for numerical control machining of impeller sort and blade sort, and also can improve modeling and machining efficiency of impeller sort and blade sort. |
