The Data Management System Of Mechanical Three-dimensional Product(PDM)

The present paper based on to face to the system development method of the module, the adoption COM/ DCOM programming way, combine VC++6.0 develop to connect with UG/OPEN API, according to the PDM of technique thought combine to gather PDM and system of CAD, developed a set of product information management system that has the spare parts information management, the spare parts parametric design. In the course of research of the topic, carried on the analysis to the function of PDM first, then according to the concrete circumstance of the business enterprise, through the analysis of the requirements of the system, a set of cases was developed by the Unified Modeling Language (UML), and then the system model was determined by the IDEFO, one of the system design approach. Considering the system characteristics of integration and combination with UG/OPEN API, a component-based system integrated scheme was chosen. To constructed the essential technology which the system involved to carry on the elaboration, The database uses which to this system has carried on the choice, According to PDM thought and database model design theory, Has constructed the relations components information database, Then has realized the components information classified management in the system, Components information increase, deletion and edition, Components engineering plat and graphic model examination; Elaborated the parametric modeling method, Introduced the UG software three dimensional parametric design, At the same time...
