1 Overview The continuous development of modern technology in the manufacturing industry, the promotion and application of new equipment, new materials and high-tech means, the manufacturing process is also rapidly improving in the process of engine production and development, while the technical performance of aviation products is special, and the products must be guaranteed during the production process. Processing quality, it is still difficult to break away from tooling, especially in the development process of new machines, the characteristics of multi-variety, single-piece and small batch production are formed. The development of form requires a short development cycle, while tooling design and manufacturing take up a certain development cycle and cost. How to shorten the tooling design, manufacturing cycle, improve the processing quality of the device, and reduce the cost has become the focus of our attention. 2 Imagine The traditional design, manufacturing and management methods of tooling make special tooling design, long manufacturing cycle and relatively high manufacturing cost, which is difficult to meet the needs of current new machine development. According to the current development of manufacturing industry, people are advocating lean manufacturing, highlighting innovation, and demanding higher requirements from design methods, design quality, manufacturing cycle, tooling cost and management. This involves the innovation, manufacturing and management concepts of tooling design methods. Update. At present, we have increased investment in informatization construction, using information management platform to change traditional design and manufacturing ideas, and fully utilize modern design tools, manufacturing and management methods to maximize the level of tooling design, manufacturing and management. 3 combination concept In the 1990s, we applied combination tooling and selected the tooling that was flexible enough to be assembled by standard components in a short period of time to realize the function of special tooling. It can solve single-piece and small batch production, and is suitable for new machine development and trial production. However, the design and assembly of traditional combination tooling are still manual. Each assembly requires the use of semi-finished products in the front process as standard parts, and the assembled device structure. The preservation of photos or hand-drawn sketches, the quality of the assembly relies on experienced and skilled technical workers, objectively limiting the application of the combination tooling. With the popularization of high technology and the development of professional software, the introduction of the virtual assembly concept provides superior conditions for the design and management of combined tooling. We set out to develop a custom UG-based KBE combination tooling design and management system with research institutions. It uses a 3D UG system as a platform and seamless integration. The combination of tooling components and components is digitized, and the database is established. The user can select the standard components and components provided by the system for virtual assembly, or use the knowledge base function provided by the system to intelligently select standard components and components for virtual assembly and data implementation. Management and resource reuse. The use of special design software to realize computer virtual design combination tooling requires database support, establish a database of combined tooling components, and establish classification according to the functions of combined tooling components, which can be divided into basic parts, support parts, positioning parts, clamping parts, guiding parts, and tool setting. A few parts, such as a component library, a typical structure library and a knowledge base, the function of the component is an organic combination of components. The design idea of ​​the combination tooling is to call the CAD platform component and the standard component library to realize the standard component download and standard component replacement. Using KBE-based design systems, tooling designers are freed from heavy design tasks. On the computer, you can analyze and view the functions of each part, which can realize fast plotting and data management.
