Involute Gear Artifacts

Project Description

At the EURAMET TC Length meeting in October 2007 it was proposed to establish an international comparison on involute gear measurements. There has so far not been such an international comparison.

The comparison comprises measurements at three different gear artifacts: an involute profile artifact, a helix slope artifact and a pitch artifact. The scope will be the measurement of 28 measurement parameters at these artifacts.

Final Report 2014-04-03

The comparison has been completed and results are available in the KCDB.
