Symmetry tolerance
WebTolerance is the total amount a dimension may vary and is the difference between the upper (maximum) and lower (minimum) limits. Because it is impossible to make everything to an exact size, tolerances are used on production drawings to control the parts. When do we need tolerances? In particular, tolerances are assigned to mating parts in an assembly. … WebMar 15, 2024 · Here it is 21 - 20 = 1. Divide the Total Tolerance by two to obtain the Equal Bi-Lateral Tolerance. Here it is 1/2 = 0.5. Subtract the Equal Bi-Lateral Tolerance from the upper limit (Maximum ...
