ActiveGeometrical product specifications (GPS)—Geometrical tolerancing—Pattern and combined geometrical specification
产品几何技术规范（GPS） 几何公差 成组（要素）与组合几何规范
Application Summary AI generated
This standard specifies rules for defining and applying geometrical tolerances to patterns of features and combined geometrical specifications, such as simultaneous requirements for multiple holes or slots. It is used in mechanical design, manufacturing, and quality inspection to ensure consistent positioning and orientation of grouped features on parts like engine blocks, transmission housings, or precision assemblies. The standard applies across industries including automotive, aerospace, and general engineering where GPS principles govern dimensional and geometric accuracy.
