Abstract: Aiming at the large production consumption of machine tools and complex environmental emissions,the collected data was heterogeneous and came from multiple levels of parts,workshops and enterprises,which was difficult to directly apply to life cycle assessment problems.The transfer rules and mapping relationships between high-level and low-level resource environmental load data were studied.A multi-level data distribution calculation method was proposed,a life cycle inventory acquisition model based on multi-level data allocation and a quantitative model of environmental impact emission inventory based on product life cycle were established.Life cycle assessment index system and environmental impact classification were established.The environmental impact assessment of machine tool product life cycle was analyzed.Combined with the survey data,the environmental impact assessment of the machine tool was carried out,and the proposed method was verified.

Key words: multi-level data distribution, machine tool, life cycle assessment, environmental impact assessment
