A new modularization method of heavy-duty machine tool for green remanufacturing

The green remanufacturing constitutes a type of recycling form that adapts to ecological and economic requirements and an important part of the advanced manufacturing technology. In order to improve the green remanufacturing capacity of heavy-duty machine tools, in this paper a heavy-duty machine tool module division method for green remanufacturing was proposed. The main lines were based on the four design domains of axiomatic design and innovatively extended to the remanufacturing domain. In the design stage, the process of remanufacturing was considered. The modular clustering algorithm based on atomic theory was employed, which was associated with the correlation and similarity between the design parameters in the structure domain and the remanufacturing domain, for the ideal modules of heavy-duty machine tools to be discovered. Finally, a heavy-duty gantry milling machine is used as an example to verify the validity of the proposed method.
