【Abstract】 The frame of intelligent computer aided design system of plow based on PDM (product data management) and the function and technology of its three main parts, design expert system, PDM and plow CAD system were introduced. Design expert system helps the plow CAD system select the design parameters and find the faults of the assemblage drawing. PDM manages the data and files of the plow CAD system and the knowledge base of the design expert system. Finally, the development of the plow CAD software that integrates design expert system and PDM is introduced.更多还原
