| Abstract: | In the integration of CAD/CAPP/CAMsystem, the share of product's non -- geometry informa-tion (such as size tolerances, geometry tolerances, posi-tion tolerance, roughness and material's property) isvery important. In the Engine five--valve cylinder headCAPP system development, the application program in-terface (API) of Pro/Engineer, Pro/Toolkit, was usedto extract the product feature model's tolerances and ma-terial information. And the product's tolerance informa-tion and the material's property were then imported intothe CAPP system based on Oracle DBMS using the EX-PRESS language. |
