GD&T uses a combination of symbols, abbreviations, and rules to define the permissible variations in the shape, size, and position of features. These variations, or tolerances, are specified in a way that allows the manufacturer to produce parts that are within the specified limits while still meeting the functional requirements of the part or assembly. GD&T is essential for ensuring that parts are interchangeable, that they can be assembled and disassembled correctly, and that they will function reliably over time. Overall, GD&T provides a common language for engineers, manufacturers, and quality control personnel, ensuring that everyone is working towards the same goal and that parts are made to the highest possible standards.
