Uncontrolled dimensions contain two different categories of tolerances: 1) All manufacturing tolerances used up to that point (such as laser-cutting tolerances, welding tolerances and more) 2) All bend tolerances for the entire part, added together We call this an uncontrolled dimensions because there are additional tolerances to consider. The bends described in the article are for steel piping and pipelines. Within the world of tube fabrication, tolerances are specified to accommodate differences or unique characteristics in raw materials and quality as well as other factors such as the equipment being used, the machine operator or the setup parameters.
