Abstract
Measurement fixtures are developed to explain the form (circularity and cylindricity) and orientation (angularity) geometric tolerances in a Senior Level elective course on Geometric Dimensioning and Tolerancing (GD&T). The fixtures are easy to implement, cost effective, and the measurement activities are scalable to large classes. Students who participated in the course indicate in an end-of-semester survey how measurement activities relying on these fixtures can bridge the gap between the symbols in the engineering drawing and their physical meaning.
