| Facing more intense global market competition and rapidly changing customer requirements manufacturing enterprises have to change their product design and fabrication modes greatly In short time. ICAD (Intellectualized Computer Aided Design) become more and more important for manufacturing enterprises.According to the new progressing trends of mechanical product rapid development technology and the practice of developing pump CAD system by the author , the paper basically discusses primary technology of ICAD based on marine pumps , and how todesign a ICAD system . The system--SPCAD can be used on Win 9X/2000 , andhave friendly UI(User Interface), primary technique that discussed in the paper includes OOD (Object Oriented Design), measured design method , design method that bases on archetype , design method that bases on cases , design method that bases on restriction . The paper also discusses the designing progress of marine pumps. |
