Data Exchange Standard

IGES (Initial Graphics Exchange Standard) is a general graphics data exchange standard, which has been widely used for data exchange between different CAD/CAM systems. But the inherent defect of IGES makes it difficult to use in the field of automatic programming. This article focuses on the automatic programming of holes processing. Entities were labeled with different entity number, on which the hole entity could be distinguished and extracted based. The intersection lines of hole and NURBS surface could be calculated by NURBS surface intersection algorithm. The redundancy of intersecting lines is a key problem. This article gives an intuitive treatment.
