PDM system is a tool for managing product data and product development process, and the implementation of PDM system can improve the management level in the aspects of technical document management, technical document secrecy and technical document modification.

PDM is a set of advanced methods and software system for managing the technical department of an enterprise from the task book of new product design to the stereotype of product design and even the data of the whole process of product scrapping. It is the product of the combination of scientific management methods and enterprise management requirements, and a product of the combination of computer technology and enterprise culture. To put it simply, PDM is a management tool for managing product data and product development process.

The necessity of implementing 1PDM system

1. 1 technical document management

Lack of system support for technical document management. Technical documents are managed separately by the way of traditional Windows folder. With the rapid increase of product data, the traditional folder management method has been unable to meet the needs of technical document management, the relationship among product details, drawings, change orders and other data can not be clearly established, information query, retrieval and browsing become difficult, and the sharing and utilization of drawings and materials can not meet the existing needs.

1. 2 aspects of technical document modification

With the increasing number of products, the degree of serialization is higher and higher, and the number of parts borrowed is also more and more, which poses a challenge to the technical changes of designers. Designers generally use computer-aided design means, which is inconsistent with the media used in production, processing, inspection and other links, because product design changes often occur, it may form the phenomenon that the changed electronic technical documents are inconsistent with the paper medium, which directly affects the product processing quality.

Scattered stored drawings, drawing change notices, and historical drawings cannot be associated with each other, resulting in inconvenience for traceability after changes. For the borrowed parts, it is difficult to deal with the associated change, which affects the borrowing of the new product design. The change of drawing is directly related to the change of parts and related materials.

Modifications to components are usually made in the form of technical document change notices and drawing changes. If changes in product structure and materials are involved, then the production plan and inventory must be adjusted accordingly, which is difficult to ensure consistency for the manual management model.

Overview of the functions of 2PDM system implementation

2. 1 management of technical documents

(1) establish the electronic warehouse of drawings and documents by using PDM system, centrally manage the design drawings and technical documents of the electronic carrier, and associate them with related parts to form an enterprise-level technical resource database, so that the personnel of various departments can quickly find and retrieve the correct information they need according to various conditions, improve the repeated utilization rate of the design, and ensure that the data can be accessed at any time within the scope of authority control, so as to realize data sharing. Avoid illegal calls, modifications and leaks.

(2) to realize the electronic examination and approval and electronic distribution of drawings. So that the relevant personnel can carry out timely examination and approval on business trips or other circumstances, and improve the efficiency of examination and approval. Electronic distribution can improve the distribution efficiency, at the same time can reduce paper, reduce costs.

2. 2 confidentiality of technical documents

Through the integration of PDM system and file security system, the file is encrypted by software and hardware. as long as the file leaves the designated office network, the file can not be opened.

2. 3 aspects of technical document modification

The product design and production process often needs to go through many changes, and strict change procedures need to be established. The change process is as follows:

(1) apply for change to the technical document to be modified

(2) modify the technical documents after approval

(3) prepare the change notice of technical documents in accordance with the requirements of the company.

(4) the notice of change of the technical document shall be submitted for approval together with the technical document of the change.

(5) after the technical document change notice is submitted, it will automatically enter the approval process in accordance with the set examination and approval process. After the technical document change notice is approved, the technical document change notice and the changed technical document enter the PDM database with a new version. If the changed component has been borrowed, notify the person in charge of the relevant product.

Achieve the following goals through technical file change management:

(1) automatic sending of technical document change notice. Automatically send it to the relevant unit according to the issuing unit of the changed document

(2) through strict data version management, the changed data can be transmitted to ERP in time.

(3) Technical document change notice and changed file as a whole to facilitate the tracking and query of the change process.

(4) save the versions of all stages of the technical documents to facilitate access to the change process.

2. 4 data sharing

Using the integration of information systems such as PDM / CAPP and CAD / ERP, we can realize the integration of different application systems across departments and business fields, ensure the smooth flow, uniqueness, integrity and dynamic sharing of enterprise-level data and information flow, and realize dynamic tracking and feedback of the whole process, so as to effectively direct and drive the integration and control management of enterprise logistics, capital flow and concomitant information flow. Provide timely, reliable and scientific decision support for managers.

2. 5 expand the application

Through implementation, PDM / CAPP can be extended to the production workshop for application. If the production workshop has a certain hardware level through the deployment of the network, the PDM / CAPP system can be installed in the production workshop, and the workshop operators can directly query and browse the product data managed by PDM / CAPP through the workshop terminal, and the data can be updated and managed synchronously, and finally realize the paperless industry in the workshop.

3 problems needing attention in the process of implementing PDM

3. 1 clear implementation objectives

No matter how good the system is divorced from the reality of the enterprise, it can only be on paper. The best information system is not equal to the best implementation effect, but it still needs to be tailored. It is clear what goals need to be achieved through the PDM system and formulate a detailed implementation plan.

3. 2 staffing

PDM system is a professional information system, project implementation personnel should select senior designers, process personnel and information personnel to combine. At the same time, in order to effectively promote the progress of the project, the technical supervisor should be defined as the project leader, responsible for overseas Chinese transfer to promote the operation of the project.

3. 3 data preparation

Basic data is the root of PDM system information. Only on this basis can we build a unified information sharing platform. If the basic data is not accurate, it will lay a hidden danger for the PDM system to go online smoothly or switch successfully. It is necessary to make careful arrangements and make a clear division of labor to ensure that the data preparation work is completed in quality and quantity on schedule.

3. 4 training work

The PDM system should follow the principle of "building is the process and use is the purpose". If you want to make good use of the PDM system, training is the key. Through multi-dimensional, high-frequency training, people using the PDM system can complete the transformation from "want me to use PDM" to "I want to use PDM".

Implementation method of 4PDM system

1) establish a general project manager who is responsible for the organization, schedule, process and quality of the project. The major decisions, changes and coordination of the project shall be discussed and decided by the person in charge.

2) set up a specific person in charge of the project to be responsible for the daily management of the project. Report the unsolvable problems and focus within the project team to the project manager.

3) set up consultants. Consultants are responsible for the management mode and process specification of process data. Cooperate with the implementer to define the data organization and business organization process according to the enterprise quality system procedure document.

4) set up an implementation engineer. The implementers cooperate with the implementers to do the demand research, and are responsible for the installation, maintenance and knowledge transfer of the software.

5) set up a system administrator. The system administrator is responsible for the normal operation of the network and hardware, the assignment of permissions, the collection of operation problems and so on. The establishment of an integrated management system of product design and process planning based on PDM platform can realize the whole process and data management of product design and process design, and provide the basic data needed by ERP system accurately, timely and completely, forming a complete value chain management.
