Standard　conforming　involute　gear　measurements　were　taken　by　a　manually　operating　articulated　arm　system　and　the　respective　task-specific　measurement　uncertainties　were　estimated.　User-friendly　templates　were　developed　to　provide　almost　unambiguous　and　repeatable　measurement　results.　They　allow　the　metrologist　to　easily　detect　and　gather　the　single　measurement　points　according　to　existing　guidelines　and　standards　commonly　used　in　gear　metrology.　The　research　activities　were　carried　out　at　the　Physikalisch-Technische　Bundesanstalt　(PTB),　Germany　in　the　Department　of　Coordinate　Metrology.　Measurements　were　taken　on　a　robust　and　highly　accurate　large　gear　measurement　standard　of　PTB,　in　the　following　called　the　gear　standard.　This　gear　standard　materializes　a　left-hand　and　a　right-hand　gear　as　well　as　a　spur　gear.　The　1　m　outside　diameter　of　the　gear　standard　is　similar　to　the　gears　used　in　wind　power　plants.　A　commercial　articulated　arm　coordinate　measuring　system　was　used　for　the　measurements.　A　high　temperature　stability　of　+/-　0.2　degrees　C　was　provided　to　minimize　thermal　influences.　The　results　of　profile　and　helix　measurements　will　be　presented.　This　worldwide　first　investigation,　on　the　basis　of　a　calibrated　involute　gear　standard,　gives　users　of　the　articulating　arm　system　quantitative　information　on　a　task-specific　performance　of　a　representative　gear　measurement.
