General Tolerances Study Guide
Achievement of exact dimensional control is not possible due to fabrication processes being imperfect. To ensure that a design can be fabricated, it is necessary to permit variation on every dimension specification. The allowable amount of fabrication error (tolerance) specified on a drawing is normally calculated on the basis of functional requirements. The achievable level of manufacturing accuracy is determined by factors such as process capability. Product cost can be directly impacted by the specified allowable tolerances, and care should be taken to avoid specifying tolerances that are unnecessarily small.
