Abstract
Aviation part manufacturing has the features of high processing accuracy, high added value, high customization, long processing cycle, and large material removal, which leads to complex carbon emission characteristics and high-carbon emission intensity throughout the entire manufacturing process. With the increased awareness of the “dual carbon” strategy, green and low-carbon development has become a necessary route for the aviation manufacturing industry. To this end, this paper focuses on the entire manufacturing process of aviation components and defines the carbon emission boundaries of the entire aviation manufacturing operation. The carbon emission characteristics of each process in the entire aviation part manufacturing are analyzed. On this basis, combining the advantages of the improved value stream mapping, the carbon emission modeling and evaluation method for the entire process of aviation part manufacturing based on the bill-of-carbon is proposed, so as to achieve the fine characterization of carbon emissions and comprehensive evaluation of carbon efficiency. Finally, the feasibility and effectiveness of the proposed method are verified by the entire manufacturing process of rib-web parts. This paper can provide methodological support for the refined modeling of carbon emissions and carbon efficiency evaluation of large aviation parts, and lay a theoretical foundation for energy saving and carbon reduction in future aviation part manufacturing.
