Best Practices of Tolerance Stacking - In The Loupe

Tolerance stacking, also known as tolerance stack-up, refers to the combination of various part dimension tolerances. After a tolerance is identified on the dimension of a part, it is important to test whether that tolerance would work with the tool's tolerances: either the upper end or lower end. A part or assembly can be subject to inaccuracies when its tolerances are …
