Abstract

The method about directly getting the geometric information and parts information from the CAD graphic database system is a technique to make CAD/CAPP/CAM system integration. NURBS can make all curves have the same mathematic representation in the CAD/CAM system, it also as the international standard in STEP standard of the industrial product geometric, which was promulgate at the ISO. The method was described in this article about how to read useful information about generated to NURBS curve from the DXF file by Auto-CAD, it proposed open-CNC system and CAD/CAM software integration solutions, and establishing a CAD/CAM integration in new ways.
