In modern industrial production, 60%-90% industrial products require the use of mold, mold industry has become the foundation for industrial development. According to the Forecast Technology Association international production machinery manufacturing industry, twenty-first Century 75% parts rough machining, finishing 50% need to be done by the mold, including automotive, appliance, communication, petrochemical and construction industries are the most prominent.

Die as a high value-added technology-intensive products, its technical level has become an important index of measuring the manufacturing level of a country. Early in the CAD/CAM technology is still in the early stages of development, CAD/CAM is mold manufacturing industry to absorb the application. The current domestic mold manufacturing enterprises around 20000, and every year 10%~15% of the speed growth. In about 40000000000 yuan mold industrial output value, self-produced their own mold enterprises accounted for about 2/3, 50%~60% enterprise application of CAD/CAE/CAM/PDM technology. CAD/CAE/CAM technology is a research hotspot in the mold development, education and training and application.

A, die CAD/CAM system for increasing degree

With the rapid development of the importance of mold industry as well as the CAD/CAM technology is widely recognized mold and die industry, in recent years, CAD/CAM developers put a lot of manpower and material resources, the universal CAD/CAM system transformation for the CAD/CAM system of Die & mould industry dedicated, in view of the characteristics of various types of mold, has launched a dedicated system user-friendly, integrated and intelligent, by the vast number of mold workers. For example, Israel Cimatron company launched Quick series of products, in the series of environmental unified, use a unified database, complete the product design, 3D entity model, on the basis of automatic classification, convex, concave die structure formation and completion of die design, convenient for automatic NC processing of punch. And as the British DELCAM company launched PowerSHAPE system, including PSMoldmaker module, is for the mould assembly design expert system of mold manufacturing, injection molding, automatic complex blowing mold mold structure and core pulling mechanism, automatic generation of parting surface, processing information is automatically package, and the output can be directly to the PowerMILL module, automatic processing program. SpaceE 3D CAD/CAM system of Japanese shipbuilding information system, also increased the module design for injection mold. Japan UNISYS Corporation dedicated to plastic mold design and manufacturing system CADCEUS is also quite characteristic, the system integration of the plastic product design from the shape of the product design, mold design to mold production and all required functions, associated with emphasis on 3D design and 2D view, reflects the technical progress of the pleasant and integration of.

Two, system integration scheme for mold enterprise CAD/CAE/CAM Technology

With the mold industry technology progress and international competition is becoming increasingly fierce, the mold industry demand for CAD/CAM system is also changed to require support from product information management integrated system for the whole process of design, analysis, management and processing from the modeling tool only. In recent years, a scheme of integrated CAD/CAE/CAM system is a lot of research institutions and companies have developed for mold enterprise, showed a higher utility level. Such as the Shanghai Jiao Tong University national die & mould Engineering Center in digital manufacturing, system integration, reverse engineering, rapid prototyping / mould and computer technology has already formed the ability the full range of solutions, can provide mold development and engineering services, comprehensively improve the level and quality of mold enterprise. And as the Zhejiang University sun Technical Developing Company, can provide a full range of product design, 3D modeling and NC programming, reverse engineering, three coordinates measurement, analysis and design, mold technology training and mould CAD/CAE/CAM technology development for enterprise support. Beihang Haier software company launched CAXA brand series of CAD/CAE/CAM software is also able to provide a full range of the mold engineering solutions for customers.

Notably, the international famous CAD/CAM Technology Group is trying to make digital products integrated into the CAD/CAM platform. Due to the digital analysis of the product is widely used in the fields of aerospace, automotive, electronics, medical equipment and heavy machinery, so the simulation software for the growth of the CAE market. According to the life cycle management of the world's leading product (PLM) of the senior market analysis company Daratech predicts, to 2007, the CAE market growth rate will remain at 10.3%.

The manufacturer's requirements by reducing the physical prototype, improve product quality to reduce the cost and speed to market demand, which is particularly prominent in the mold manufacturing industry. Therefore, to strengthen the analysis and Simulation of the early in the design process, will help reduce the demand for physical prototype, and improve the flexibility of digital design. For example, NXNastran will be integrated into the EDSCAE product package, will further strengthen the analysis of important driving design technology, helps the user to constantly develop new products, while reducing costs, shorten product time to market. In another example, Dassault group have MSC's NastranCAE technology products, integrated into the CATIA system, and obtained the Toyota Corporation of Japan's favor.

Therefore, in the mold CAD/CAM technology in the integration of digital analysis technique, complete CAD/CAE/CAM solution, is an important development direction of current.
