Geometric dimensioning and tolerancing symbols and their use.

Question

Accepted Answer

Geometric dimensioning and tolerancing symbols are used to specify the dimensions, tolerances, and geometric characteristics of a part.

GD&T symbols are used to communicate design requirements and ensure proper fit, function, and interchangeability of parts.
Some common GD&T symbols include position, concentricity, perpendicularity, and flatness.
These symbols are typically placed on engineering drawings and provide precise instructions for manufacturing and inspection processes.
GD&T symbols help control variations in size, form, orientation, and location of features on a part.
For example, the position symbol indicates the allowable deviation from the specified location of a feature.
Understanding and correctly interpreting GD&T symbols is essential for design engineers to ensure the desired functionality and quality of a product.
