Speaking of manufacturing informationization, it has to say that process informationization, it seems to play only an auxiliary role in the entire informationization process of the enterprise, but in fact, it plays an important role in the entire informationization project. It is connected to the design at one end and the production at the other. It is the key to product quality, delivery cycle and control cost. It is also the data hub of informationization in other departments. Its application is the prerequisite for successful information construction.
When it comes to the domestic process planning system, it is impossible to say that Axter, a veteran manufacturer who has been studying in the field of domestic manufacturing information technology for 14 years, has a deep understanding of the technological needs of domestic enterprises. As early as 1998, Axter people used the forward-looking vision and down-to-earth style to create a new concept of XTCAPP system. After 10 years of development and improvement, XTCAPP system has become the mainstream software in the domestic market, market share. More than 40%, it is oriented to the whole process of product production technology preparation, focusing on the data of the product manufacturing process, and at the same time bringing together modern management technology, so that the process design of the product is comprehensively upgraded from pure "edit card" work to product-oriented The new realm of process design and process information management has laid a solid data foundation for the comprehensive implementation of information technology in many enterprises. Let's take a look at the importance of process informatization for the company through the CAPP project of a large domestic diesel engine manufacturer.
Basic information about the company:
The company is a key enterprise in the research, development, manufacturing and sales of internal combustion engines supported by the state. Its products are widely used in heavy-duty vehicles, buses, construction machinery, agricultural machinery, power generation, irrigation and drainage, and ship power. It is a typical specialized production enterprise. The production plant, production line specialization and high degree of automation have formed a multi-variety and multi-batch production mode. According to the changes in the market, the speed of new product development is accelerating. At the same time, the company gradually develops toward the trend of internationalization, and its management level is continuously improved. Under continuous improvement, its process production organization has the following characteristics:
• The increasing number of specialized, digital, and flexible production lines has changed the previous steel-based, single-production model.
• Produce multi-variety and multi-batch mixed-flow production modes according to orders and forecasting plans.
• Adopt TS16949 and ISO9000 management mode to gradually form the management of product life cycle and adapt to the mode of international management.
• After years of digital investment, the company has a hardware platform for on-site electronic signage management and network-wide operation, but currently only realizes the informationization of the unit.
• The company has gradually developed into a core processing enterprise with product design, assembly and key parts processing, which requires effective management of many satellites and supporting enterprises.
• When companies are growing rapidly and expanding their mergers and acquisitions, they form large-scale conglomerates across regions.
Problem
With the deepening application and promotion of enterprise informationization (the company started the ERP and PDM upgrade implementation work in 2005, the software selected ERP and PLM software developed by two very famous international manufacturers, but in the information integration In the process, it was found that a large amount of process data and manufacturing BOM lacked an effective management and data foundation. Although the solution that has been launched also has some processing technology and the ability to manufacture BOM, but the effective management of the entire process information, there are the following three Aspects of the problem:
1. With the rapid development of enterprises, product updates and deformations are increasing, and the demand for process design and production management is increasing. However, due to the lack of necessary tools and tools, it is not obvious that computer efficiency is improved. Such as data can not be shared, file format is not uniform, enterprise knowledge is difficult to popularize, etc.;
2. Although the enterprise can meet the needs of current production in terms of process design and management, from the perspective of enterprise implementation of informationization, there is a big gap between the means and the management.
3. According to the trend of enterprise information development, it is necessary to consider and prepare for the future integration of electronic signage and MES, enterprise digital model, unified enterprise resource specification, factory and production line planning system.
Analysis and solution
As the production of manufacturing industry gradually shifts to the mode of collaborative manufacturing of the entire industrial chain, process research also puts different requirements on process planning according to the different roles of enterprises in the industrial chain, which can be generally divided into the following aspects:
• Production organization planning of the product
At present, the manufacturing industry is constantly changing its customer demand, and it is necessary to continuously introduce new products. The company's products vary greatly in quantity and quantity, and the organizational mode of production shifts to a multi-product mixed flow mode. At the same time, due to the continuous improvement of the automation of production equipment, how to quickly coordinate the various production resources of the enterprise is also the content that must be refined in modern process planning.
Modern process planning is an important basic support for “digital factoryâ€. The connotation of process planning has broken through the original model to incorporate enterprise modeling, production process planning, production organization process management, process data analysis, processing simulation, etc., such as UGS eM-Planner (Process Planner) is such a process planning software. These contents play an important role in the rapid response and accurate production of the production organization planning of products in agile manufacturing and lean production management. Although these contents are reflected in the traditional process planning, the performance is vague, discrete, and the data accuracy is not enough, which does not meet the requirements of agile manufacturing and lean production management.
• Product material organization planning
The organizational planning of product production can be said to be a model of product material organization. For example, in the automobile production industry chain, the OEM (main engine factory) is mainly engaged in product design, product assembly and production of key parts. Most of the materials of the products are made up of The supporting plants on the supply chain are completed and many parts are completed by multiple suppliers. How to coordinate and manage the entire industry chain collaborative production is the key factor for rapid product production and control of production costs. At present, the manufacturing industry is constantly changing its customer needs, and it is necessary to continuously introduce new products. The rapid response to the organization data of production is the basis for the rapid organization of production. When enterprises want to achieve agile manufacturing and lean production management, the production organization planning of products must be Refined and precise.
• Processing route of parts
The processing route of parts and components is a model of the production organization of the enterprise. These data are relatively perfect in the enterprise, but the degree of data organization and refinement has not yet reached the requirements of agile manufacturing, mainly in the process management level of the management data, from the processing route It can be divided into two categories: large route and component processing route. The former is mainly the flow management of parts and components according to the workshop or unit, and the latter is the circulation between processing steps. Because of the separation of the two, it is feasible in the manual management mode. However, under the conditions of informationization, it can not meet the requirements.
• Research on processing methods of parts
The research on the processing method of product parts is an important work of process design. In agile manufacturing and lean production management, it is not only necessary to study the processing methods of parts and processes, but also more importantly, the production line layout, material flow optimization, rational distribution and automation of equipment, etc. Both are included in the design and management of process data.
Selection is a guarantee of success
It can be seen from the previous analysis that modern process design has covered all aspects of the production organization of the enterprise, not just the traditional CAPP just for the preparation of process documents. To this end, the company analyzes and compares the software provided by software developers at home and abroad according to its own characteristics, and finally believes that the XTCAPP products developed by Beijing Axter meet the needs of enterprises. The reasons are as follows:
1. Because XTCAPP products are process design and management software developed based on database technology. The software has good data interface with other systems. In addition to obtaining the drawing number, drawing name, material, etc. directly from PDM and CAD, it can also retrieve and browse all the design image files at any time, and get the latest design change list at any time. And related data. XTCAPP is a professional production process design platform that can quickly and easily derive and replicate new design results based on typical data according to various design formats required by the enterprise. The most important thing is that XTCAPP has the knowledge management of data management, which can realize the accumulation and use of historical experience data. At the same time, the basic data management of XTCAPP can also realize the management of TS16949, providing a historical basis for process analysis, maintenance and improvement.
2. As a basic tool for process designers, XTCAPP provides a good design working environment. In addition to the typical process card preparation environment, the most important thing is to link the flow chart, process card, product structure and historical data to provide very practical. The visual editing environment greatly improves work efficiency and quality of work.
3. The networked XTCAPP organically links the process design department of the enterprise with the workshop management department to form a dynamic process implementation data monitoring system.
Facts have proved that the choice of the enterprise is very correct. After the application of the XTCAPP system, the contradiction that plagued the enterprise to promote TS16949 has been greatly alleviated. The technicians put their main energy into the process design and process management, and established a perfect data system. Provides a strong data foundation for product production and improved analysis.
Focus on the whole, cross the data island to information integration
Since the 1990s, the company has gradually implemented information technology projects, from stand-alone applications to network applications. However, due to the blind pursuit of advanced and individualized needs in the early stage, it has not been analyzed and implemented from the overall informationization, resulting in a large number of information islands. Since the implementation of XTCAPP, the company's data system has gradually opened up, and finally formed an integrated information system with design, process and production as the main line.
It is not difficult to see from the successful case of informationization of this enterprise that process informationization is indispensable. In the process of enterprise's overall informationization, process informatization is the key link to link up and down, and bears the important task of connecting design and production. However, at present, there is a problem in China's manufacturing enterprises that pays insufficient attention to process informationization. Most companies only use CAPP as a “small process†in the process department, and the essence of the process is: how CAPP provides services for enterprise production, which is what we call “big craftâ€.
On the one hand, the formation of this status quo is due to the lack of popularization of the overall informationization of domestic enterprises, and the narrow understanding of process informationization. On the other hand, local CAPP vendors rarely have the ability to develop from a global perspective. Product's. At this point, Exeter is undoubtedly at the forefront. The core concept of XTCAPP product development is “serving for integrationâ€, focusing on the management of the entire process system of the enterprise, and has taken the lead in the concept. It is believed that with the continuous improvement of the overall level of China's manufacturing informationization, the application of process planning systems will continue to expand, and process informationization will be more and more valued by enterprises, and will gradually play its role in the design, production and management of enterprises. The important role of substitution.
