| Abstract: | In 5 axis machining accuracy verification of sculptured surface, the intersection of normal vector on meshes of designed part with the tool swept volume is a difficult point. In this paper, we present a new algorithm of NURBS curved surface subdivision. Such an algorithm is based on ray tracing algorithm, and the properties of tool swept volume is also taken into account. Finally, the data structure of tool swept volume is described in details. |
