The Application of Geometrical Product Specification (GPS) - Compatible Strategies for Measurement of Involute Gears

The article "The Application of Geometrical Product Specification (GPS) - Compatible Strategies for Measurement of Involute Gears" appeared in the November/December 2019 issue of Gear Technology.

Summary
During the revision of ISO 1328-1:2013 Cylindrical gears — ISO system of flank tolerance classification, ISO Technical Committee TC 60 WG2 delegates discussed proposals that the standard should be modified to ensure that it is compatible with the ISO Geometrical Product Specification (GPS) series of standards (Refs. 1-3). This seems sensible because the gears are geometrical components, but after reviewing the implications, it was rejected because ISO TC 60 WG2 did not think the gear manufacturing industry was ready for such a radical change in measurement strategy. The feasibility of the implementation of gears into the GPS matrix of standards has been carried out and the results conclude that this is practical, provided some key issues related to measurement uncertainty and establishing appropriate KPIs are addressed.
