PDM: Physical data model, that is, physical data model. However, PLM spare parts data resource platform based on Internet is developing rapidly at home and abroad, and its advantage lies in multi-format support. For example, the PCOM2.0 platform of Cartier Company in Germany contains hundreds of parts data resources, which support the original formats of mainstream CAD systems such as Pro/ENGINEER(Creo Parametric), SolidWorks, SolidEdge, Inventor, AutoCAD, CATIA and UGSNX. Download the required data resources. In addition, they also include IGES, STEP, STL and other intermediate exchange formats, as well as multimedia software formats such as JPG, BMP, 3D MAX and Google SketchUp. Its Chinese platform is linkable.partcommunity, and its data resources involve standard parts, fasteners, bearings, springs, industrial products, motors, industrial electricity, pipeline accessories, solenoid valves, pneumatic valves, cylinders, hydraulic components, hardware and so on. The downloaded CAD model can be directly used for local assembly and product development, which can basically meet the daily needs of mechanical and electrical product designers.

PDM in network

PDM: protocol independent module

These modules can support IP, AppleTalk and IPX to meet specific network layer requirements.

Preparations for implementing PDM system

(1) PDM concept training for enterprise personnel. In the application of PDM, people's role should be particularly emphasized, which provides an optimal operation mode of man-machine mixed operation. "People" in enterprises are the main body of PDM implementation. Only when top managers, middle-level cadres and grass-roots cadres have representatives to understand what PDM is and what PDM can do, can enterprises effectively understand the expectations of enterprises at all levels, effectively tap the needs and objectives of PDM, and thus ensure the quality of PDM implementation.

(2) Full support from the top management. The application of PDM system in technical departments was originally due to a large number of CAX technologies, which led to the generation of a large number of electronic data. It will inevitably lead to changes in corporate culture and the working mode based on this corporate culture. If we want to ensure that this trend is moving in the right direction, we must get the recognition and continuous support of business leaders.

(3) The overall planning of enterprise informatization construction. The PDM system construction process of an enterprise will exist for a long time with the development of the product design department of the enterprise. In order to ensure that PDM can be organically combined with enterprise's future information construction and future e-commerce, it is safe to hire an experienced consultant to investigate and demonstrate the current situation and future development competition of the enterprise under the guidance of the consultant, and to specify a preliminary plan for enterprise's information construction, and to build PDM system under the guidance of this plan.
