PDM is really a kind of "broad management" software, which can manage all data that can be finally transformed into computer description and storage, such as product structure and configuration, part definition and design data, CAD drawing files, engineering analysis and verification data, manufacturing plans and specifications, NC programming files, image files (photos, modeling drawings, scanning drawings, etc. ), product specifications, software products (programs, libraries, etc.).
PDM can be widely used in various industrial fields. However, each field has its own characteristics and requirements, and the application level is different, so there is no general PDM system to adapt. In the process of enterprise information integration, PDM system can be regarded as an integration framework. Various applications, such as CAD/CAM/CAE, EDA, OA, CAPP, MRP, etc. , will be directly integrated into objects in various ways, such as application interface, development (packaging) and so on. In this way, all product data distributed in all parts of the enterprise and used (run) in various applications can be highly integrated.
Especially for manufacturing enterprises, the survey shows that in Western Europe, the generalized cost of a spare part was as high as 500 euros (measured in euros) as early as 1975, and climbed to 126 1 euro in 1500- in 1998. The reason for its high cost is, of course, besides the increase of materials and processing costs of parts, an important factor is that enterprises have introduced information systems such as PDM/ERP, which has greatly increased management costs. Therefore, in product design and various management links of enterprises, it has become the knowledge of more and more foreign enterprises to consider the rapid increase and rising cost of parts and use information system itself to slim down the types of parts and components.
Reducing the types of parts is a complex task, which requires the efforts and cooperation of many departments to achieve results. The key is to establish an enterprise-level spare parts data resource base, enrich the data resources of local PDM and optimize the storage structure, so that designers can easily find the needed data resources and be willing to search instead of designing and calling new parts.
In addition, the huge and rich 3D model platform built by cloud computing is also a good choice, such as PLM part data resource platform-Part Community. In foreign countries, this kind of network service is called "parts library" or "data resource library". Among PLM users in Europe, America and Japan, PARTcommunity (PCOM for short) is as popular as well-known online platforms such as blogs and SNS. At the beginning of 20 10, PARTcommunity 2.0 (PCOM 2.0 for short) was officially launched in Germany, and its simplified Chinese PCOM 2.0 site (linkable.partcommunity) has rich spare parts data resources for registered users to browse and download for free. A PDM product that can meet the needs of enterprise applications should have nine functions, including document management, workflow and process management, product structure and configuration management, viewing and marking, scanning and image service, design retrieval and parts library, project management, electronic collaboration, tools and "integration" functions.
PDM and ISO900X
The PDM system can automatically realize the process required by 9X, reduce the cost and improve the work efficiency. PDM can provide enterprises with tools to implement the 9X standard.
Product data management is of great significance for realizing enterprise information integration, improving enterprise management level and product development efficiency, and it is one of the important technologies in the field of computer application.
