The intermediate GD&T class offers a brief review of the concepts established in the basic class followed by a wider range of datum topics including degrees of freedom, mating envelopes and datum feature shift. The main focus of the class is on positional tolerance. Single and multiple frame applications of position will be presented using animated illustrations applied to single features and patterns of features. Computational and graphical methods for positional tolerance verification are discussed.
Functional gauge design for the inspection of single features and patterns using virtual condition calculations concludes the course.
