Research on Key Technologies of 3D Model Database Based on Network Platform

Due to the low efficiency of traditional manufacturing industry design, it cannot achieve reuse and resource sharing, it is necessary to design 3D model database based on network platform. ISO 13584 (parts library, PLIB) standard can transfer the data of supplier library. According to plib-42 standard, the part library is constructed, and the step method is used to share and exchange the part library information, through the network interface and Internet, we can build a web-based shared resource library. According to the geometric view expression technology, the interface of Pro / E, CATIA and inventor is developed. This paper starts with the technical research and engineering application, the construction of part library and the development of geometric programming interface are introduced in detail, the format and development method of geometry program file are proposed, Completed the standard parts model library system. Provide design resources for modular design system to realize the information integration and network collaborative design of part resources, It is of great significance to improve the speed of mechanical product design and development.
