Abstract: Aiming at the carbon emissions in the machining system,a carbon emissions quantitative method was proposed.The characteristics of materials,energy consumption and carbon emissions in machining system were analyzed,the generalized boundary of the system was defined and the multi-source characteristic of the carbon emission was discussed.The multi-source carbon emissions quantitative method of machining system was discussed in detail,in which not only the carbon emissions caused by materials and energy consumption was considered,but also the carbon emissions caused by auxiliary materials such as cutting fluids,cutting tool and metal chip processing was considered.The quantitative methods for each kind of carbon emission were provided respectively,in which the key factors were also studied.The experiment was performed to verify the feasibility of the proposed method.

Key words: machining system, carbon emissions, quantitative method, generalized boundary
