A Design Feature-Based Method for Assessing the Whole Life-Cycle Carbon Footprint of Machine Tools
In the face of the severe climate change challenge of global warming,reducing carbon emissions throughout the life-cy-cle of machine tools has become a crucial task.Starting from the design stage,with the goal of reducing carbon emissions throughout the whole life-cycle of machine tools,it is the basic work of low-carbon design of the machine tool to study its carbon emission characteris-tics and the correlation of its related design elements.To evaluate the carbon footprint of machine tools throughout their life-cycle in the early design stage,a method for assessing the whole life cycle carbon footprint of machine tools based on design features was proposed for the design stage.The concepts of machine tool system features(relationship features and operational features)and individual fea-tures(geometric features,technical processing features and material features)were introduced to characterize the hierarchical constraint relationships between machine tool components,and the expression model of machine tool design scheme based on design feature was established.The carbon emissions activities throughout the whole life-cycle of machine tools were classified into six categories of feature-related activities based on design features,and the correlation mechanism between design features and carbon emissions activities was established.A quantification method for carbon footprint based on design features was proposed,and a whole life-cycle carbon footprint assessment model for machine tools was established.The feasibility of the proposed method was verified by calculating and analyzing the carbon footprint of a circular saw blade saw machine throughout its whole life-cycle.
