A stated or theoretical size serves as a reference point for manufacturing processes. This designated size, often expressed as a whole number, facilitates communication and standardization across engineering drawings, specifications, and production workflows. For example, a pipe may be referred to as having a 2-inch designation, even though its actual manufactured diameter may deviate slightly due to tolerance allowances.
The implementation of a standardized reference size streamlines design, manufacturing, and assembly processes. It reduces ambiguity in technical documentation and simplifies the selection of mating components. The historical context of this concept is rooted in the need for interchangeable parts and efficient mass production, contributing significantly to advancements in engineering and manufacturing industries.
