These are best addressed before the first sample by reviewing the complete mating interface, not by tightening every drawing tolerance.<\/p>\n<p>Use tolerances selectively. Dimensions that establish the tooth mesh, chain engagement, shaft fit or assembly datum deserve explicit measurement methods; non-critical molded surfaces can often use a more practical general tolerance.<\/p>\n<\/section>\n<section class=\"imp-section\">\n<h2 id=\"inspection\">First-article and production acceptance<\/h2>\n<p>Agree the inspection condition, datums and measuring method before sampling. The first-article report should cover the drawing CTQs and then be paired with a functional check in the real assembly or a representative fixture. For gears and sprockets, that can include mesh or chain engagement, runout and bore relationship; for custom molded parts it can include fit, fastening and loaded features.<\/p>\n<p>Production control should follow the same CTQs rather than replacing them with a long list of easy-to-measure cosmetic dimensions.
