ActiveGeometrical Product Specifications(GPS)--Methods for the assessment of departure from roundness--Measurement of variations in radius
产品几何量技术规范(GPS) 评定圆度误差的方法 半径变化量测量
Application Summary AI generated
This standard specifies methods for measuring and assessing the deviation of a workpiece's circular cross-section from a perfect circle, using radius variation measurements. It is applied in precision manufacturing and quality control for components such as bearings, shafts, and hydraulic parts, where roundness tolerance directly impacts performance and fit. The standard is used in metrology laboratories and production inspection to ensure compliance with geometric product specifications (GPS).
