| Abstract: | By researching on NURBS modelling method, the authors have successfully realized a new modeling function in NURBS bi skinning surface via complex curves on SuperMan CAD/CAM integrated system, and a CAD/CAM system which is full based on NURBS method is set up. It is proved by the various examples coming from engineering application that the new NURBS method is a flexible and effective method, which is suitable for production designing and manufaction with complex external forms. |
