Recently, the 9th China International Machine Tool Show was held at the Beijing International Exhibition Center. The grand and prosperous scene of the exhibition left a deep impression on us. As the equipment manufacturing industry of equipment manufacturing industry, the machine tool is also the industrial "master machine". Its development status represents the level of China's industrialization, and to a certain extent is also the "barometer" of China's economic development. We are delighted to see China as a manufacturing power. The machine tool industry has achieved remarkable results after years of development. It is summarized as follows: First, the total supply capacity is extraordinary; second, the product category is complete; The high point sprint, developed a number of varieties with independent intellectual property rights; Fourth, the machine tool industry information technology received practical results.
China's machine tool industry has entered the world's first phalanx, and is accumulating strength for a new development leap.

However, while seeing our achievements and development opportunities, we cannot ignore the problems and challenges. Taking metal cutting machine tools as an example, the annual output of China's gold cutting machine tools has exceeded 300,000 units for several years, and in 2004 it exceeded 350,000 units. This is not a small number, and the international rankings have entered the fourth place, which is a machine tool producing country. On the other hand, CNC machine tools, which represent the advanced level of machine tools in the world, have made great progress, but the total amount is only 50,000 units per year, and about 70% are economical. Although there are many varieties of domestic high-end CNC machine tools, they still have not got rid of the situation of relying on imports. Last year, China imported 3.5 billion US dollars of metal processing machine tools, while exports only 500 million US dollars. In the process of upgrading the machine tool industry from “low-end products” to “high-end products”, the gap is very obvious, that is, high-level high-tech equipment still depends on imports. In addition, the technical research and development capabilities of the machine tool industry need to be improved, and the innovation capability of enterprises is enhanced. Technological innovation is also an important embodiment of the vitality of enterprises.

For manufacturing companies, including the machine tool industry, how to improve the competitiveness of enterprises and the long-term and rapid development is a systematic and complex problem. In brief, it includes three factors: excellent products, good operation and stable market customers. relationship. Chinese enterprises often pay enough attention to the latter two, of course, this is necessary, but the former - excellent products can not be ignored for enterprises, from the perspective of long-term development, especially in today's economic global integration Even more competitive market conditions are even more important. Practice has also proved that launching better products faster than competitors is the most effective way for companies to create profits. The success of a product largely determines the success of the company. In order to improve the market competitiveness of the enterprise, the machine tool industry enterprises must improve the ability of design and development and create excellent products. In addition to the preconditions of R&D designers with good quality, it is imperative to establish a software environment for product R&D and design. Less.

The fully parametric 3D design system represented by Pro/Engineer software provides a complete solution for the entire process of manufacturing. It combines PTC's family of software products to create a complete product development system (PDS) for manufacturing companies. The product development system includes digital model definition, digital model control, project collaboration and management, and enterprise-level product data management. The 3D design software focuses on the definition of digital models.

Product development system - creation, collaboration, control

As a high-end 3D design software, Pro/Engineer uses this software for product design. No matter which part of the design is changed, these changes will be propagated to all subsequent information. Especially for complex and systematic products such as machine tools, the use of high-end software will have a clear advantage. Complete 3D modeling capabilities improve product quality and speed to market, Pro/Engineer's application layout, skeleton and reference relationships for Top-Down design of large and complex products, enabling the creation of effective product digital models, especially in design changes When you serialize your product or borrow data, you will have a deep understanding. Pro/Engineer software can also greatly improve production efficiency by automatically generating related mold design, assembly instructions and machine code. Pro/Engineer software can simulate and analyze virtual prototypes and optimize designs without virtual prototypes. The way simulates the actual force and motion and analyzes the possible problems of the product under these conditions. Early in the design phase to gain insight into product performance to improve product performance and design better products. At the same time save time and cost. In addition, Pro/Engineer software supports compatibility with a variety of CAD tools (including related data exchange) and industry-standard data formats. Together with other PTC products, it can form an effective sharing of digital product data environments among team members, based on product development systems. Optimize the digital product value chain and improve business processes.

Product development system optimizes digital product value chain

Dalian Machine Tool used Pro/Engineer software to design a variety of machine tools such as vertical machining centers, CNC machine tools and high-speed machining centers. In the process of designing products with Pro/Engineer software, users realize that 3D modeling can intuitively and accurately perform structural design and layout adjustment. Global interference checking, motion analysis, and finite element analysis can reduce design errors and improve design quality. Automated BOM generation to avoid missing parts. Application of the corresponding collaborative management platform Pro/Intralink can realize collaborative design, share data, improve design data reuse, and make enterprise electronic files more secure and reliable. Therefore, in the design stage, the cost and error rate of the product are minimized, and finally the production cycle of the product is greatly shortened, and the market is quickly put on the market, bringing incalculable economic benefits to the enterprise.

Cincinnati Machine uses Pro/Engineer software to reduce product development time, such as the Pro/Engineer software's sheet metal function Pro/SHEETMETAL, which completely redesigns and builds the machine's protective cover in about a month. The sheet metal unfolding map is automatically created, and the parts can be bent with different bending factors. This ability allows users to create solid models directly instead of 2D drawings. Part manufacturing is passed directly to the CAM system through the flattened bend data file, eliminating the need for drawings. Pro/Mechanica's finite element analysis function Pro/Mechanica ensures that important parts are strong enough and as light as possible. However, the greater benefit is the powerful engineering data reuse of PRO/E, which replicates all parts, assemblies and engineering drawings from an earlier designed subsystem and is modified to suit current requirements, which can significantly reduce project time.

The 3D software solves the visual and intuitive design that can't be realized by 2D, product virtual assembly, motion simulation, interference check and publicity renderings. High-end 3D design software can better support systems and top-down design processes for large and complex products such as machine tools, as well as analysis optimization and processing. Establish an enterprise product research and development system to improve the company's research and development capabilities and core competitiveness.
