The Chinese name of PDM is Product Data Management. PDM is a technology used to manage all product-related information (including parts information, configuration, documentation, CAD files, structures, permissions information, etc.) and all product-related processes, including process definition and management. For PDM, domestic and foreign scholars and experts have been in theory and technology? I have done a lot of in-depth research and discussion. I think that PDM is a kind of software that is very widely managed. Any data that can be converted into computer description and storage can be managed. It is called manufacturing product data. Housekeeper's PDM.
PDM can solve the problems of many industries in the manufacturing industry. The welding equipment industry has its own characteristics and has commonality with other manufacturing companies. Can PDM solve the problems in the R&D and manufacturing of welding consumable equipment? Should we pay attention to those links in the implementation process? What benefits can it bring to the business? This article discusses the following aspects:
1. Problems in R&D and manufacturing of welding consumables production equipment
(1) A large amount of product information, which mainly reflects that a welding consumable production equipment is composed of multiple components and hundreds of basic components, each of which is composed of a plurality of basic components.
(2) The product information structure is variable, and it can be structured data information or unstructured information.
(3) The product design process is complicated. It is a process from overall refinement to localization, from equipment surface modeling to internal component design. It contains many attributes, materials and feature information, including a large number of mathematical models and drawing information.
(4) In the process of R&D and manufacturing of welding consumables equipment, the product R&D department and the process department will gradually accumulate a large number of drawings and documents in electronic form, with low sharing of such information, slow data transmission, and business. The data is difficult to integrate and the level of data management is backward. These problems directly restrict the company to shorten the product development cycle.
Second, the important links that should be paid attention to during the implementation of PDM
A set of PDM products that can meet all aspects of enterprise application should have document management, workflow and process management, product structure and configuration management, viewing and annotation, scanning and image services, design retrieval and parts library, project management, and electronic collaboration. The functions, tools and "integrated parts" functions, combined with the characteristics of the welding consumables manufacturing industry, should pay attention to the following specifications and management during the implementation process:
(1) Formulation of product code
Product coding is one of the most important tasks in all work, and it is related to the success or failure of the system. Once it is determined, it cannot be easily changed. original? Some coding systems have been unable to adapt to the increasing demands of the product development process. What are the specific terms and codes that need to be combined with the welding material production equipment to establish a set of capabilities? ? Cover all product ranges, and try to use international common standard coding, reduce non-standard parts, and facilitate the computer to query the coding system. The following is a screenshot of my company code:
(2) Reasonable allocation of components and parts libraries
In order to improve work efficiency, combined with the characteristics of PDM system, data reuse between components and parts is realized, so that users can easily find drawings, technical documents and product data related to components and parts.
(3) Document and various data management
Decrease the design of the drawing document due to different names and versions. Establish a set of drawings, documents archiving, storage and query system, so that users can quickly and easily find and browse the required drawings and documents.
(4) Workflow management and project management
Strictly regulate the design release and change process to avoid errors and emphasize cost savings. Workflow management is established based on the workflow management model of enterprise welding equipment development. Mainly in the two aspects of approval management and change management, submit an operation or task to the relevant personnel through the computer to complete the development and editing. ? Review, approve, or approve work to control the process.
(5) Defining the product structure
Product-independent product components are not within the designer's jurisdiction, reflecting the hierarchical relationship between welding equipment, components, and parts in a product structure tree. On the basis of the structure tree, query other attributes of these components, such as material and weight, so that the file information describing the components and parts can be organically connected with the relevant parts on the tree node to realize product data management of different welding equipment.
(6) User rights management
Do a good job of authority management, and do a good job of communication between departments. For each functional department, personnel of different levels and departments should have different usage rights for PDM systems to ensure the security of data information. According to the organizational chart and personnel function distribution table of each functional department, browse and modify permissions for different users.
Third, the benefits of applying PDM in welding consumables manufacturing equipment manufacturing
(1) Improve the association? Sharing, can realize the electronic management of enterprise technical documents and materials. Through the backup and sharing of the PDM system, it is possible to save design models and drawings with various storage media such as optical discs and tapes, improve storage security, improve drawing retrieval speed, reduce storage space, and ease the difficulty of drawing and file management personnel. The integrity and security of the technical information.
(2) Application process management to standardize product design management. In the traditional design mode, the process of product development is controlled by manpower, and the human subjective consciousness plays a decisive role. In order to develop a new product, the company usually pre-develops a feasible, detailed and thorough development plan, but Among many enterprises, only a few product development projects are completed on schedule, mainly? Because: there are many links in product development, the process concept is unclear, and any problem in any link will affect the entire development cycle of the product. Without software such as PDM, the progress of product development cannot be tracked in time, and the PDM system can support the work. The management of the flow, therefore, not only makes management more standardized, but also tracks the progress of product development and controls the quality of the design.
(3) Optimize the use, improve product design efficiency, and support parallel design. Designers can share information through the PDM system. Different versions of the part model and drawing information can be used in the shared database in time to be used by other authorized designers, so the design can be parallelized and help to improve product design. s efficiency.
(4) First-class enterprises rely on processes and process reengineering to promote institutional changes in the enterprise product development group to meet the challenges faced by modern manufacturing.
Fourth, the conclusion
When the welding consumables manufacturing equipment and PDM are organically combined, it is possible to realize product-centric, computer network and database technology, and integrate all product-related information and processes in the enterprise design process and production process. To make product data consistent, up-to-date and safe throughout its lifecycle, providing a synergy for engineers and technicians. The same working environment. PDM already? To become an indispensable tool for manufacturing enterprises, it will become an important means to enhance the competitiveness of enterprises.
