Application of td/xtpdm system in Zoje machine tools in 2003, Zoje began to plan a new "coordinate" of informatization. With the help of xtpdm system, Zoje comprehensively optimized the design means, further improved the management quality of the design department, enabled the enterprise to maintain its vitality in an increasingly competitive environment, accumulated more experience for the successful implementation of xtpdm, and provided valuable materials for the implementation of PDM projects in the machine tool industry

enterprise and project overview

ZOJE Machine Tool Co., Ltd., founded in 1939, is a large backbone enterprise in the national machine tool industry and an important production base for horizontal boring machines, CNC milling and boring machines and milling and boring machining centers in China. In 2002, the company won the honorary title of top ten enterprises in the CNC output value of the machine tool industry, and won dignity and honor for China's equipment manufacturing industry

since the country put forward the major guideline of "promoting industrialization with informatization, promoting informatization with industrialization, and realizing the leap forward development of social productivity", informatization has gradually become the main melody in the wave of accelerating China's industrialization. As a backbone enterprise with decades of history, the informatization construction of Zoje machine tool is urgent. The main problems are that the product has a long cycle from R & D to production, a large amount of design, up to 1000 drawings for each product, and up to 100000 electronic drawings of the design department. According to the drawings designed in series, the assembly relationship is complex, the design changes frequently, and the manual management is cumbersome. These problems are as follows:

design drawings and document management

Zoje's products are single piece, small batch, customized design, and tens of thousands of design drawings. There is no unified standard for traditional CAD software drawing, which results in that the drawings designed by an engineer and other engineers can not generate reports for the products of the drawings, but can only be counted by the designers. Marking the cumbersome details and reports has become the bottleneck of the design. Enterprises do not have the link of drawing and document management. They mostly rely on the file tools of the operating system to realize drawing and document management. When there are many user files, the management is extremely inconvenient and not intuitive. The information query method is single, and it is not convenient to sort by designer, time, product attribute, etc., so it is not convenient to query the required information. When the design drawings and documents are frequently modified and many versions are generated, it is more inconvenient to manage. The storage methods of drawings and documents are not unified, resulting in easy loss or damage of drawings

serialization of product design

improving the serialization of products is an effective means to reduce the number of parts and shorten the product design cycle. However, because the parts designed by each designer at different times can not be fully and effectively used by other designers, or even for a long time, they can not find the corresponding parts themselves, resulting in the designers' inability to quickly and accurately find out similar parts. Although the factory has a set of modular management methods, due to the diverse needs of users, it is impossible to fix a single module for management, resulting in frequent changes in each module. Designers do not know which module to use in the design

data security risks

strengthening the confidentiality of design drawings and design documents has always been a key consideration in the factory. The traditional paper-based data are kept by a specially assigned person, while CAD drawings and documents are kept in the form of electronic data. The degree of sharing is greatly improved, and the security of confidential information is also greatly threatened. The development of Intranet makes this form more severe. Enterprises urgently need a safe and flexible security measures

implementation process

in order to comply with the development of the enterprise, Zoje machine tool signed a PDM Project cooperation agreement with AIX users when purchasing equipment in August 2003. The enterprise has put forward higher requirements for information construction, including higher security, availability, large data volume, high performance, etc. industry characteristics are also another focus. The project has experienced several parts from implementation to secondary development and product development, and achieved remarkable results

1) implement tdmini version to standardize the design documents, and carry out a lot of secondary development work according to the design characteristics of the machine tool industry, which meets the design requirements of the machine tool industry and greatly improves the design efficiency

2) implement xtpdm r3.5 design data management, design change management, design process management and other modules

after nearly one year of implementation and construction, the entire PDM Project has been in the overall acceptance stage, playing an irreplaceable role in Zoje

implementation steps

the implementation of Zoje's PDM Project is mainly divided into two stages:

* the first stage: CAD pdm drawings and files and changes should be used for the launch with the strong support of the state

from the investigation in August 2003 to May 2004, the implementation and application of minitd, xtpdm35 drawings and files and changes were mainly completed, and a TD design and product data management environment was established in the enterprise design department CAD design standardization and data standardization were carried out. CAD continued to develop and maintain from the beginning of the project to the basic end of the project. At the same time, TD was carried out according to the drawing characteristics of the machine tool industry. One of the reasons was a lot of customization and development work. After secondary development, TD software is more perfect and flexible, especially for the machine tool industry, which greatly improves the market competitiveness. In xtpdm, data organization and management are carried out according to product categories, providing methods for reusing tens of thousands of old drawings of enterprises. Customized development and customization are carried out according to the special drawing number standards of the machine tool industry. It is almost applicable to the whole machine tool industry, automatically generating various product reports required for production, and establishing a management mode for safe access to product data

implemented the PDM change module, and established a set of customized templates for change management according to the change process of the enterprise. After the implementation and application of this phase, the technology center has formed a working environment with PDM as the core. The data has been centrally managed and the accuracy has been gradually improved, which has established a solid work foundation for the implementation of phase II

* phase II: PDM three-dimensional integration, design process management system and configuration management go online

for key parts and special parts of the enterprise, SolidWorks is used for drawing, and some parts are drawn using pro/e. Phase II first implemented the three-dimensional process, developed three-dimensional drawing specifications and management specifications, and gradually imported the three-dimensional drawings into the PDM system for unified management. According to the review process of the design department, a set of design process management template suitable for use has been customized for the enterprise. The effect is good in a small range. Now it is planned to be popularized and applied in the whole design department. The configuration module correctly sets the operation parameters of the experiment according to the experiment request, which lays a good foundation for the design and rapid establishment of general products and subsequent ERP management

the second stage was completed from the beginning of June to the end of July 2004. The whole implementation laid a solid foundation for the capp/erp system that the enterprise is planning. In the process of implementation, the key of PDM implementation is how to standardize the drawing of machine tool industry. Without much change to the specification of machine tool industry, designers can quickly draw drawings and use PDM for management. In the application of the whole project, Zoje factory has set up a special project team to conduct simulation tests on the design change management module and the design process management module. After actual measurement and improvement, the specific application routes of the change module and the process module have been determined to ensure the reliability of the whole line

implementation benefit

several months' operation shows that the xtpdm system is stable and reliable, solves the existing problems in the drawing and document management, workflow management and safety management of the plant, provides an information sharing platform for the technical personnel of the plant, and makes the information management to a new level. It greatly shortens the technical preparation cycle of new product development, cancels the repeated work in the process of technical development, makes the accuracy and consistency of data reach 100%, greatly shortens the new product development cycle, improves the work efficiency and reduces the product cost

so far:

(1) through a large number of adaptive development of the Design Star software, without much change to the design specifications of the machine tool industry, it fully meets the needs of designers to quickly draw drawings and can use PDM for management, which greatly improves the design efficiency

(2) there are more than 110 products under the management of PDM system, 17600 drawings, and the list of three major design reports, purchased parts and standard parts of the enterprise are quickly generated through the PDM system. The PDM system has become the largest, most complete and most reliable product database of Zoje design department, and an indispensable tool for design engineers to obtain design data and work together

(3) by optimizing the product development process, the development and design of deformed products are shortened by 15%

(4) through the implementation of CAD, the design means have been improved and the drawing cycle has been significantly shortened

(5) through the implementation of PDM system, the data archiving, maintenance management, inspection release, change control and other links are controlled according to the purpose of ensuring the accuracy of product data, so that the controlled product data can become a reliable and available data source

(6) PDM product reports greatly reduce the workload of repeated sorting and data entry in report making, so that the work of the original week can be basically completed in less than one day

summary

the machine tool industry is a basic industry related to the national economy and the people's livelihood and the cutting-edge construction of national defense. Its degree of development can basically be used to measure the development level of a country's manufacturing industry. Due to its importance, it has become one of the industries that earlier implemented enterprise informatization in China. Zoje has successively invested heavily in introducing CAD and other design software, and has established some simple management systems. The early informatization investment has laid a certain foundation for enterprises to establish modern scientific management. The management innovation of enterprises is not the best, only better. In 2003, Zoje began to plan a new "coordinate" of informatization. With the help of xtpdm system, Zoje comprehensively optimized the design means, further improved the management of water products in the design department, so that the enterprise could maintain its vitality in the increasingly competitive environment, accumulated more experience for the successful implementation of xtpdm, and provided valuable materials for the implementation of PDM projects in the machine tool industry
