![]() ![]() ![]() Material Solutions Analysis (MSA) Phase Tutorial In practice, it is impossible to achieve 100% accuracy. So basically, 100% accurate is just a theory. Even machines can not produce 100% accurate parts. ![]() Determining optimized tolerances is therefore always advised. However, a product’s functionality may be impacted by loose tolerance. The rejection rate and production costs can go up with tight tolerance. Without tolerances, it is economically impossible to produce parts that closely match. That helps engineers to figure out if the part can be assembled freely or not. The maximum and minimum distance (clearance or interference) between two features or parts can be determined using tolerance stackup analysis. In engineering drawings, tolerances are mentioned against dimensions if that dimension is critical to quality (CTQ). The process of determining the effects of the cumulative variation permitted by given dimensions and tolerances in parts or assemblies is known as “ Tolerance Stack up” or “ Tolerance Stacking“. In this article, we will learn more about tolerance stackup analysis and different types of tolerance stack ups with examples. By using Tolerance Stackup Analysis, we can find the best way to balance the tolerances in parts, lowering the cost of making it and that also ensures that the part fits in the assembly even in the worst-case scenario. Tolerance Stackup is a methodology used in industries to determine how the cumulative tolerance of parts affects the whole assembly. ![]()
