The Design of Machine Engineering Data Management (MEDM) Based on Distributed PDM

Abstract

Current manufacturing industry is facing an increasing challenge to satisfy customers and compete in market,and because of lacking communication among different product development stages often causes consistency problems in product lifecycle. In this paper, we first analysis the principle and the limition of distributed PDM,then we design the machine engineering data management system (M-EDMS) based on the principle of distributed PDM, the whole system is composed of two modules::the architecture design of M-EDM system,which have three layers,the first layer is the M-EDM system support level, the second layer is the core function of M-EDM object layer, the third layer is the user layer;and the function design of M-EDM system,which have the rights and organizational management module, workflow / design process management module, Project management, product structure and configuration management module, electronic collaboration module, image processing module and so on.This proposed system designment scheme is well suited for various applications for medium and small enterprises and has good prospects.
