GB/T 24632.2-2024 Geometrical product specifications (GPS) - Cylindricity - Part 2 : Specification operators 1 Scope This standard specifies the complete specification operator for cylindricity of complete integral features. This standard is applicable to the cylindricity of complete integral features. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The complete specification operator defines the transmission band for the cylindricity surface, together with an appropriate stylus tip geometry. Note: In practice, it is unrealistic to hope to achieve comprehensive coverage of the cylindrical feature given by the theoretical minimum density of points (see Annex B) within an acceptable time span using available technology. Therefore, more limited extraction strategies are employed that give specific, rather than general, information concerning the deviations from cylindrical form. 4.2 Probing system 4.2.1 Probing method A contacting probing system with a stylus tip, as defined in 4.2.2, is part of the specification operator. 4.2.2 Stylus tip geometry The theoretically exact stylus tip geometry is a sphere. 4.2.3 Probing force The probing force is 0 N. 5 Compliance with the specification For proving conformance or non-conformance with the specification, ISO 14253-1 applies.
