    Abstract :

    - Selective assembly is an approach for reducing the overall variation and thus improving the quality of an assembled product. In this process, components of a mating pair are measured and grouped into several classes (bins) as they are manufactured. The final product is assembled by selecting the components of each pair from appropriate bins to meet the required specifications as closely as possible. This approach is often less costly than a tolerance design using tighter specifications on individual components. It leads to high quality assembly from relatively low precision components. A relatively smaller clearance variation is achieved than in interchangeable assembly, with the components manufactured with wider tolerance.Selective assembly is carried out in three stages using metaheuristic techniques. These metaheuristic techniques give the best combination. Thus, very high precision assemblies are obtained using the proposed method and minimize the assembly clearance variations and at the same time to minimize surplus parts without sacrificing the benefits of selective assembly. The proposed method is applied for a complex assembly such as ball bearing
