  • Best Practices of Tolerance Stacking

    2018 8 10 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 stacked up incorrectly.
