摘　　要：为研究清洁切削过程的碳排放,讨论加工系统碳排放的边界。以铣削Ti-6Al-4V钛合金为研究对象,量化其切削过程中产生的碳排放,对比不同清洁切削方式和切削参数对碳排放和加工表面质量的影响。结果表明:若只考虑机械加工过程,LN_(2)冷却产生的碳排放最少,其次是低温CO_(2)冷却、微量润滑、浇注冷却,但在整个加工系统的碳排放中,低温CO_(2)冷却产生的碳排放最少,其次是微量润滑、LN_(2)冷却、浇注冷却。对比浇注冷却,低温CO_(2)冷却、LN_(2)冷却、微量润滑都能提升工件表面质量和刀具寿命。另外,提高切削速度能降低加工过程的比碳排放,但过高的切削速度会加剧刀具磨损而产生更大的碳排放量。To study the carbon emission of the clean cutting process,this paper discusses the boundary of the carbon emission of the machining system.Using the milling of Ti-6Al-4V alloy as the object of study,the carbon emission generated during the cutting process is quantified,and the effects of different cooling methods and cutting parameters on the carbon emission and machining surface quality are compared.The results show that if only the machining process is considered,LN_(2)cooling produces the least carbon emission,followed by CO_(2)-snow,MQL,and flood cooling,but among the carbon emissions of the whole machining system,CO_(2)-snow produces the least carbon emission,followed by MQL,LN_(2)cooling,and flood cooling。Compared with flood cooling,CO_(2)-snow,LN_(2)cooling,and MQL can improve the surface quality of the workpiece and tool life.In addition,the increase of cutting speed can reduce the specific carbon emission of machining process,but excessive cutting speed can increase tool wear and result in higher carbon emissions。
