Geometric Dimensioning and Tolerancing: Changing the Concept

Geometric Dimensioning and Tolerancing (GD&T) is a system that defines and communicates engineering tolerances through symbols, allowing for more precise and consistent measurement in manufacturing processes. This system changes the traditional concept of using traditional measurements and specifications, providing a more efficient and effective way to communicate design requirements. By using GD&T, engineers can accurately define the allowable variation in dimensions and geometric characteristics of a part, leading to improved quality, reduced costs, and streamlined production processes.
