What is GD&T?
Geometric Dimensioning and Tolerancing (GD&T) is a symbolic language for specifying and communicating permissible limits of imperfection for machine part features in order to guarantee assembly and operation prior to drawing release. Applied to 2D engineering drawings or, better, to 3D CAD models, it is the only basis for truly functional tolerance stack-up analysis, and for get-it-right-the-first-time manufacturing and coordinate metrology.
Because of its complexity, most GD&T is largely “decorative” and requires “interpretation,” making it dangerous, tending toward useless. To actually deliver its amazing gifts, it must be carefully “encoded” and uniquely “decoded,” which are the foundation concepts in this training video set.
Presented by Bill Tandler, founder and president of Multi Metrics Inc, and produced by Quality Digest and RocketSpots.
