the the puter-aided design and assembly. Application of CAD technology to create ponent library the typical fixture library, standard and user archive fixture optimization design, assembly fixtures for users dimensional solid. Cutting process simulation tool, both to provide users with the correct fixtures ponents supporting the program, but also the accumulation of experience, understand the market demand, and continue to improve and perfect the fixture system. Fourth, GM Economic fixture versatility direct impact on the economy. Modules, modular fixture system, a one-time investment is relatively large, the only fixture system reconfigurable and scalability features a wide range of applications, common good, fixture utilization, faster recovery of investment to reflect the economic good.
