| Abstract: | To solve the problem of product data exchange and sharing among CAx systems, an information integration method was proposed based on the STandard for the Exchange of Product model data (STEP ) and STEP-NC. A CAD/CAPP/CAM/CNC integrated system model was established. The system employed STEP and STEP-NC to express product data in form of neutral file, by which data exchange and sharing could be realized in the integrated system. Furthermore, the key integration technologies were discussed ,which included manufacturing process information modeling, file conversion from STEP AP203 to AP224 and automatic feature recognition. |
