Geometric Tolerancing is a system used in engineering and manufacturing to define the allowable variations in the shape and position of parts. It provides a clear way to communicate how much a feature can deviate from its ideal form, ensuring that parts fit together correctly and function as intended. This system uses symbols and annotations on technical drawings to specify tolerances for features like size, form, orientation, and location. By using Geometric Tolerancing, designers and engineers can improve the quality of their products while reducing costs and production time. It helps in minimizing errors during manufacturing and assembly, leading to better overall performance and reliability of the final product.
