In 1988, The American Gear Manufa
23、cturers Association recognized the need for establishment of standards for the calibration of gear measuring instruments. The AGMA Calibration Committee was formed between April 1989 and their first meeting in February 1990. Between 1995 and 1999, this committee, as members of the Committee on Gear
24、Metrology (COGM), was instrumental in the establishment of the Oak Ridge Gear Metrology Laboratory for the purpose of calibrating gear artifacts traceable to the National Institute for Standards and Technology. The AGMA Calibration Committee, between 1990 and 1998, developed and published three nati
25、onal standards on calibration of gear measuring instruments: ANSI/AGMA 2110-A94,MeasuringInstrumentCalibrationPartI,InvoluteMeasurement,ANSI/AGMA 2113-A97, Measuring Instrument Calibration, Gear Tooth Alignment Measurement, and ANSI/AGMA 2114-A98, Measuring Instrument Calibration, Gear Pitch and Run
26、out Measurements. Thesestandardscoveredelementalmeasurementsspecifiedintheaccuracyrequirements ofANSI/AGMA2015-1-A01,AccuracyClassificationSystem - - TangentialMeasurements for Cylindrical Gears. In1999,thecontentofthesestandardswascombinedandsubmittedtoISOasaproposed work item. As a result, ISO TC6
27、0/WG2 used this as the basis for development of ISO 18653:2003,Gears - - Evaluationofinstrumentsforthemeasurementofgears,andISO/TR 10064-5:2005, Code of inspection practice - - Part 5: Recommendations relative to evaluation of gear measuring instruments. During the ISO development period the Calibra
28、tion Committee decided that supplemental information,onmeasurementsystemconditionsforcalibration,accuracyrequirementsand uncertainty determination, was desirable to have in an AGMA Information Sheet. This resulted in the publication of AGMA 931-A02, Calibration of Gear Measuring Instruments and Thei
29、r Application to the Inspection of Product Gears, in 2002. TheISOdocumentsexpandedtheAGMAworkandincludedmaterialonthedetermination of uncertainty of measurement and the introduction of spherical calibration artifacts. The naturalevolution,therefore,wastheadoptionofthetwocomprehensiveISOdocumentsas n
30、ational documents in place of the four ANSI/AGMA documents. ANSI/AGMA ISO 18653-A06 replaces ANSI/AGMA 2010-A94, ANSI/AGMA 2110-A94, ANSI/AGMA 2113-A97, and ANSI/AGMA 2114-A98 for measuring instrument calibration. The measuring methods for those standards can be found in AGMA ISO 10064-5-A06. This s
