TECHNICAL DEFINITION

In manufacturing and engineering, tolerance is the allowable deviation or range of variation from a specified nominal dimension, value, or property of a part or system, crucial for ensuring interchangeability, fit, and function of components within an assembly.

BACKGROUND

Engineering tolerance is the permissible limit or limits of variation in:a physical dimension; a measured value or physical property of a material, manufactured object, system, or service; other measured values ; in engineering and safety, a physical distance or space (tolerance), as in a truck (lorry), train or boat under a bridge as well as a train in a tunnel ; in mechanical engineering, the space between a bolt and a nut or a hole, etc.
