The Research And Development Of Engineering Drawing Management System Based On Workflow Technology

As an integrated platform for enterprise information,PDM has been applied to more and more enterprises. But high level of technology,the computerized degree,and higher investment are needed in implementing PDM. The application of PDM is restricted in middle-small manufacturing enterprises. EDM is one of the main functions of PDM,and can meet the need of the engineering data management for enterprise. But the conventional EDM system pays more attention to the management of static state data only and is short of the management of dynamic design flow.Being associated with the project "the development of numerical process planning integration platform faced the agility manufacture ",which is sponsored by Sichuan Province,this dissertation puts forward that the application of PDM for middle-small manufacturing enterprises should make EDM be the kernel matter. The system structure and the application method are proposed based on the PDM principle. According to the workflow way,this dissertation applies the workflow's calculation model to the engineering data management and builds up the model of workflow for the production design process. A new engineering data management system,which is based on the product data management,and is suited to computer integrated manufacture environment,and is able to fit to the workflow management to the distributing circumstance is developed. This system breaks through the localization of the static management pattern,and implements the dynamic management on the whole lifecycle of product from designing to end product,and keeps the consistency about drawing information which includes the assemblage information,the examine and approve information,the bill information,on the whole lifecycle.The key technologies are discussed in detail in this dissertation about the system development,which includes procedure interface,database,system security,the management of system data,the creating of Bill of Material,automation pick-up of title bar information and scanning about CAD Drawing based on the control.
