Optimal part matching and joining sequence in non-rigid assemblies for improved geometric quality
Paper in proceeding, 2022

For assembly of non-rigid components, given the scanned geometries, a self-compensating assembly line has shown to be capable of steering the assembly process, finding the optimal assembly properties, e.g., joining sequences. However, the computational burden of optimization for each assembly step is still limiting the physical application of this concept. This paper proposes a strategy for identifying the optimal matching of the components and the corresponding joining sequences to reduce the computation time, bypassing repetitive optimization steps. The results show that the proposed method simultaneously provides the optimized component matching and joining sequence leading to a simplified computation process.
