What is GD&T and purpose

Question

Accepted Answer

GD&T stands for Geometric Dimensioning and Tolerancing. It is a system used to define and communicate engineering tolerances.

GD&T is a symbolic language used to specify the dimensions, form, orientation, and location of features on a part.
It provides a standardized way to communicate design requirements and ensure the interchangeability of parts.
GD&T allows engineers to define tolerances more precisely, reducing manufacturing errors and improving product quality.
It helps in controlling the variation in the manufacturing process and ensures that parts fit and function together properly.
For example, GD&T can be used to specify the position of holes on a mating part, ensuring proper alignment and assembly.
GD&T symbols include straightness, flatness, circularity, concentricity, perpendicularity, and many more.
By using GD&T, engineers can accurately convey design intent and ensure that parts meet the required specifications.
