Basics of Tolerance

Every manufactured part must meet certain specifications. Tolerances describe the range of acceptable measurements in which a part can still perform its intended function. Tolerance ranges typically describe a linear measurement. Surface texture can require a certain tolerance as well. Tolerances attempt to balance the use of a product with the cost required to produce that product. Improper tolerancing can result in parts that do not function in the way they were intended or parts produced with dimensions that are more precise than necessary, adding unwanted cost to production. After the class, users will be able to describe common methods used for part tolerancing, as well as the impact tolerances have on part production and quality.
