 Engineering tolerance

Engineering tolerance refers to the permissible limits of variation in a physical dimension or measured value of a manufactured part or system. It defines how much a dimension, such as length, width, height, or weight, can deviate from the specified value, while still allowing the part to function properly in its intended application. Tolerances are crucial in engineering and manufacturing because: 1. **Fit and Function**: They ensure that parts fit together correctly and operate as intended.
