| Abstract: | This paper develops an effective integrated CAM system to overcome the technical difficulties in the 5 coordinate machining of the impeller. The system employs the NURBS method to model a blade and a impeller, and searches the intersection of curves and surfaces as well as tool path solution. More about the system is to build the post process model and machining simulation model, and machine with DNC communication. |
