When two or more components are assembled linearly, the assembly variation will be the sum of the component tolerances. To achieve high-precision assembly, the components have to be manufactured with close tolerances. But, it will increase the product cost. If the assembly variation is to be less than the sum of the component tolerances, selective assembly is the only solution. In selective assembly, the components’ dimensional distributions are divided into equal number of selective groups and the appropriate selective groups are assembled interchangeably. In this paper, the best combination of selective groups for a linear assembly, which consists of three components having similar dimensional distributions, is obtained using particle swarm optimization (PSO). The combination obtained has resulted in minimum assembly variation. The assembly variation obtained by interchangeable assembly is 36 μm. By implementing the proposed method, the assembly variation is reduced from 36 μm to 7 μm.
