ActiveGeometrical product specifications(GPS)—Matrix model
产品几何技术规范（GPS） 矩阵模型
Application Summary AI generated
This standard defines the GPS matrix model, a framework for structuring and relating geometrical specifications, tolerances, and verification principles for product geometry. It is applied in mechanical engineering and manufacturing industries to ensure consistent interpretation of design specifications across design, production, and quality inspection processes. The matrix model supports the selection and chain of standards for dimensional and geometrical tolerancing, enabling interoperability and reducing ambiguity in technical drawings and measurement protocols.
