Abstract: In the practical manufacturing process,more than one process alternatives can be adopted to achieve the same technical requirements for the same component.But the indicators of processes such as material utilization,energy consumption,production time and cost-effectiveness are quite different.For this problem,a new low carbon manufacturing evaluation indicator-carbon benefit was proposed by combining with the proposed indicators,and its calculation method was discussed,in particular the carbon emissions calculation method.A low carbon decision-making model of multiple processes aiming at the carbon benefit maximization was established,and the dynamic characteristics of carbon benefit along with the capacity were analyzed.A case of an automobile transmission gear was introduced to analyze and verify the feasibility of proposed model.

Key words: carbon benefit, low carbon manufacturing, process decision-making, gear machining
