Tolerancing

Tolerancing is the process of defining acceptable limits of variation in the size, shape, or position of a manufactured part. It ensures that parts will fit together properly and function as intended, despite minor differences that occur during production. By specifying tolerances, engineers set acceptable ranges to maintain quality and compatibility, balancing precision with practicality and cost. Ultimately, tolerancing helps create reliable products by clearly communicating how much deviation is acceptable in each component.
