Application of PDM technology in the implementation of iso/ts16949:2002

iso/ts16949:2002 quality management system - organization and application of automotive production parts and related maintenance parts ISO9001 below, our technicians introduce the characteristics and ordinary protection of digital display electronic tensile testing machine; special requirements for: 2000 integrates QS9000, VDA6.1 and other systems, and emphasizes process control, continuous improvement and defect prevention from the perspective of product design, In order to reduce the quality fluctuation and waste in the auto parts supply chain, it forms a systematic and complete quality management system, which embodies the essence of quality management in the modern international auto industry. TS16949 standard requires the help of computer system for a large number of data files and process management. However, in the face of a wide variety of information systems, how to choose the appropriate system to meet the needs of TS16949 standard implementation process is a problem that automobile supporting enterprises are eager to solve. PDM system provides a guiding method to solve this problem

1. PDM system's support for TS16949

pdm system is based on software and takes products as the core. It integrates all product related information and product R & D process information into a unified management technology. It can be seen from two aspects: horizontal, that is, product management. PDM system takes the whole life cycle of products as the main line, and is specifically expressed as the representation form of products at different stages of the life cycle, From sales Bo

m - Design BOM - process bom - manufacturing BOM to the production information required by ERP. PDM system can help organize product design, improve product structure modification, and find archived data and relevant product information in a timely and convenient manner; Vertical is process management. PDM system organizes the product R & D process in the way of project management, and can coordinate and organize all stages of the R & D workflow, such as design review, approval, change, workflow optimization, product release and other process events

2. The three key points of s16949 standard under the implementation of PDM system

the implementation of TS16949 standard in PDM system involves almost all modules of project management, configuration management, document management and change management. In the process of implementation, it is necessary to generally focus on fishing and grasp its main needs for PDM as the key points, which can be summarized into three aspects: process management, document card and document data statistics

2.1 process management (APQP)

APQP is the core tool of "16949", which runs through the whole process of standard implementation. It defines five major stages of enterprise product design, including planning and specifying projects, product design and development, process design and development, product and process confirmation, feedback, review and corrective measures

apqp is a continuous process with strong logical consistency between stages, between processes, and between inputs and outputs. Therefore, enterprises should emphasize the application of process methods and system methods in planning

pdm project management can incorporate APQP as a vertical main line to manage the horizontal whole product life cycle. For the above apqp5 stage, the implementation method in PDM is as follows

1) plan and specify the project stage. The work plans of the five major stages in APQP can be defined and refined in workflow management, specific to each work sub process. When creating a project task, you can reference the workflow of this project and distribute the task on it. Each APQP plan is unique. Different products have different design procedures. Different time and order of customer needs and expectations also affect the complexity of products. However, the APQP plan of the same type of products is similar. We can standardize the process of the same type of products, establish a general template, call it directly during the development of the same product, and use it after the development of similar products is slightly modified

the process of project task distribution is to specify the input and output of each stage or sub process on the APQP process template, specify the executor and task start/end time of each stage and sub process, and give them corresponding project roles, so that they have the corresponding permissions of PDM modules involved in this project

2) product/process design and development stage. After the project is started, project members perform their project roles and perform assigned tasks driven by workflow. After the submitted quality documents and drawings are reviewed and signed by Guizi, they are hung under the project task tree as intermediate documents for project members to view

3) product and process confirmation and feedback stage. The implementation process of tasks is the implementation process of the whole APQP plan. The implementation engineer macroscopically supervises and regulates the implementation of the plan through the Gantt chart of the project, and the management personnel understand the task status of project members through the Gantt chart to balance the workload of personnel

4) review and corrective action stage. In case of change requirements of archived documents, the change management module of PDM can be used to master the different change states of documents through version control and new changes. After the change takes effect, the notice shall be issued to relevant departments in time to receive feedback and confirmation, so as to achieve the improvement of implementation and quality

2.2 compilation of document cards (generation of document card templates and associated filling of document cards) and printing

1) definition of quality document template 2 TS16949 implementation of the format of quality documents is relatively standardized, and the template of each type of card can be established with the help of the drawing function of CAPP process cards, such as APQP plan, FMEA, workflow diagram, control plan, etc. When defining output, just call the template and fill in the corresponding content. At the same time, it also supports customized document format output. Designers can choose one method according to the situation, as shown in Figure 1

2) linked filling of data. Relevant templates are set with corresponding associations. After the product source data in the same project is entered in one type of template, it will be linked to fill in the similar items of other templates. At the same time, the modification and deletion of data are also linked

3) bi directional document classification management: a complete set of ts16

949 management documents are generated vertically with the product as the main line, which are connected to the corresponding nodes of the project tree as task output, so that the quality documents of any process at any stage of the project can be easily viewed; Horizontally, take the document template type as the classification and summary of each type of document, and the documents of the same type of different products are classified in the same directory, so as to facilitate the reference and comparison of different products in the same process operation

4) document query, permission and printing: support the classification query of documents, and provide a variety of retrieval methods. In addition to the code, name and classification in the general query, it also includes types such as by project, by task and different approval status of documents. Permissions are designed according to different confidentiality levels of documents, and personnel with different project roles can only browse documents with corresponding permissions. File application printing, and support the batch printing function of associated files

2.3 document number graphene resin coating can be used for statistical analysis of data such as heat insulation, aircraft lightning strike, corrosion protection, rain erosion, hail and sand storm corrosion protection

1) realize quality data management in the way of object management: PDM takes products as the core, and its data can be divided into five categories according to the manifestation of products in different stages of their life cycle, namely: workflow data, design BOM data, quality document data Process BOM data and manufacturing BOM data are shown in Table 1. Product quality document data is the guarantee of normal design and production of products, so it should also be used as product source data for unified management

although there are great differences in the expression of these data, they are encapsulated in the way of objects in the PDM system for unified version control, and each completes a relatively independent data life cycle (Design - electronic review and signing - archiving - change)

2) data analysis: the front-end PDM system reads the production process data in the quality file through the data acquisition interface; Through the integration of the back-end and the statistical analysis software, the main structure of the testing machine structure is to output the collected production process data to the statistical analysis software for processing, and encapsulate the analysis and processing results in the form of objects

3) knowledge reuse: encapsulate commonly used professional terms and statistical data in PDM knowledge base. When quality documents, such as control plans, can read the data of the knowledge base through relevant connections, automatically fill in human quality documents and build benchmarks. It avoids manual repetitive work and outputs in the document format required by TS16949

3. An aerospace molding company realizes the implementation of TS16949 standard with the help of PDM system

the company is a company specializing in the research and development, production and sales of plastic molds for auto parts. During the implementation of TS16949 standard, enterprises found that the standard has extensive requirements for implementation software, and pure quality management software can not fully meet its strict requirements on product design characteristics and process characteristics. In April, 2006, the technology center of the company began to fully implement the PDM system, which has achieved the above requirements in both aspects and achieved remarkable results. Its basic implementation architecture is shown in Figure 2

1) the seamless integration of PDM and CAPP provides a unified data platform for the integrated management of data in all stages of the product life cycle, and the automatic transformation between product design, quality management, production and manufacturing data, realizing data sharing and process sharing

2) the project management and change management module of the PDM system of the application execution layer conveniently outputs various implementation process plans and task information of TS 16949, and guides the product to successfully complete its whole design and production life cycle. The person in charge of the project can visually check the implementation of the project and the information of various tasks in the Gantt chart, and macro-control the progress of the project

3) the implementation result layer manages and archives all kinds of quality documents according to the project documents and types of documents, and is associated with the project tasks as an output. The project personnel visually view the documents and understand the relevant task information in real time. With the application and execution layer as the core, the ultimate goal of the implementation result layer is "continuous improvement", which is not only reflected in the completion of TS16949 indicators, but also the great improvement of customer satisfaction

4) the underlying database is used to store the quality record data required for the operation of the process; With the help of knowledge reuse, the creation of process templates, file templates, knowledge bases, and the automatic association and filling of data reduce the repetitive work of manual input, reduce the error rate, and improve work efficiency. This is of great significance to build a quality process for continuous improvement

4. Conclusion

the implementation and implementation of iso/ts16949:2002 is of great significance to automotive suppliers and even the entire automotive industry. The smooth implementation of standards cannot be separated from the support of information systems. PDM system combines advanced quality engineering technology to make up for the limitations of ordinary quality management software, and assists enterprises to improve the quality of product design and development stage in both workflow management and quality document data management
