Bottom-up segmentation of composite structures for cost-efficient manufacturing
This work focuses on optimizing manufacturing processes for composite products with complex geometry. The goal is to efficiently partition the 3D surface mesh so that parts can be manufactured with specific technologies while minimizing costs. For this purpose, the proposed algorithm merges the elementary units iteratively by selecting the two elements that reduce the total cost through a bottom-up hierarchical clustering algorithm. The applicability of the method is demonstrated in a case study of bus manufacturing. The results illustrate how the costs of tools, adhesives, and materials vary when a complex structure is segmented.
期刊介绍:
The CIRP Journal of Manufacturing Science and Technology (CIRP-JMST) publishes fundamental papers on manufacturing processes, production equipment and automation, product design, manufacturing systems and production organisations up to the level of the production networks, including all the related technical, human and economic factors. Preference is given to contributions describing research results whose feasibility has been demonstrated either in a laboratory or in the industrial praxis. Case studies and review papers on specific issues in manufacturing science and technology are equally encouraged.
