摘　　要：The application of cutting fluid is significantly increased in the machining sector to improve productivity.However,the inherent characteristics of cutting fluids on ecology,environment,and society shift the interest of researchers to work on environmentally friendly cooling conditions such as cryogenic cooling.Here,the effect of cutting speed and feed rate on the machining performance of the AISI‑L6 tool steel is investigated under cryogenic cooling conditions.Then,the L9 Taguchi based grey relational analysis(GRA)is conducted to investigate the essential machining indices such as cutting energy,surface roughness,tool wear,and material removal rate(MRR).The results indicate that the cutting speed of 160 m/min and feed rate of 0.16 mm/r are the optimum parameters that significantly improves the machining performance of AISI‑L6 tool steel.为提高生产效率,近年来切削液在机械加工领域的应用显著增加。然而,考虑到切削液对生态、环境和社会有影响,研究人员转向了对环境更友好的冷却条件,如低温冷却。为分析切削速度和进给速度对AISI-L6工具钢在低温冷却条件下的加工性能的影响,采用L9田口灰度关联分析(Grey relational analysis,GRA)分别对切削能量、表面粗糙度、刀具磨损和材料去除率(Material removal rate,MRR)等关键加工指标进行了实验研究。结果表明,切削速度160 m/min和进给速度0.16 mm/r是最优切削参数,能显著提高AISI-L6工具钢加工性能。
