For the purpose of design, manufacture and verification, a consistent geometrical model for the product function is required. In the product life circle, full implementation of the GPS standard is to effectively analyze, optimize and control the factors related to the quality of product geometrical dimension. It's very difficult for the designer to manage them. This paper first analyzed GPS's role in product's quality control, then typical CAx data format and interface are studied to realize data bidirectional transform. The method is proposed to integrate GPS standards in typical CAx by using TOOLKIT interface provided by Pro/ENGINEER. Associate GPS modules are embedded. Finally, integrated platform is developed. The integrated platform can reduce the application costs of GPS standards; moreover, it can achieve the automatic control and optimization of product's geometric quality.
