摘　　要：制造业是我国碳排放的主要源头,机床作为制造业的工作母机,减少其主要零部件制造关键环节的碳排放,是实现我国2020年减排任务的关键。针对机床典型零部件的全生命周期过程及其关键碳排放环节,分析机床零部件生产阶段、加工阶段、使用阶段、回收处理阶段、运输阶段的碳排放情况,提出了基于机床零部件生命周期的碳排放系统运行模型。并重点分析了包括零部件毛坯生产工艺、热处理工艺以及机械加工工艺的整个生产加工过程碳排放情况,建立了基于物料流、能量流、环境排放流的碳排放量化模型,可用于识别和分析各个阶段的碳排放情况。以某企业常用的机床典型零部件主轴套筒作为实例开展研究,计算其生命周期过程的碳排放;基于碳排放对生产加工工艺参数、加工工艺方案进行了分析与优选,提出了相应的减排策略可为我国机床零部件碳排放提供量化方法和思路,进行有针对性的节能减排。Manufacturing is the main source of carbon emissions in China, Machine tools are considered as machine run tool of manufacturing industry, thus reducing the main components marrufacturing of the key process of carbon emissions is the key step that achieve the reducing carbon task of 2020. The production, processing, using, recycling and transporting of machine tool are analysis, based on the analysis of machine tool parts life cycle stage and its key carbon emission process. A carbon system running model of machine tool parts based on life cycle perspective is presented. Then the carbon emissions quantitative model are established based on the material flow, energy flow and environmental emission flow, it can be used to identify and analyze the various stages of carbon emissions. A case of spindle sleeve is introduced to analyze, carbon emissions of the life cycle process was calculated. The process parameters and the machining process are analyzed and optimized based on the carbon emission. The corresponding emission reduction strategy are put forward which can provide quantitative methods and ideas for the life cycle management of carbon emission in Chinese machine tool parts.
