Full life cycle carbon footprint assessment of circular saw blades based on design feature modelling

In order to assess the carbon footprint of a saw blade throughout its life cycle, a new carbon footprint LCA assessment method applied to the conceptual design phase is proposed. In this paper, the concepts of product system features and individual features are proposed to describe the layer-by-layer constraint relationships between saw blade parts. A design feature-based representation model of a saw blade design solution is developed. The correlation between the whole-life carbon emissions of sawblades and design features is analyzed, a carbon footprint calculation method based on design features is proposed, and a sawblade whole-life carbon footprint assessment model is established. Taking a TC350 model saw blade as an example, the feasibility of the proposed method is verified by calculating and analyzing its whole-life carbon footprint.
