Abstract

ABSTRACT We primarily need to reduce the consumption of metalworking fluid to ensure sustainable and eco-friendly machining of aerospace alloys. The present study was planned to determine the efficiency of various eco-friendly metalworking fluid strategies for the sustainable turning of aerospace aluminium alloy (Al7075-T6) coated carbide tools under different eco-friendly metalworking fluid strategies namely dry machining, minimum quantity lubrication (MQL), Ranque-Hilsch vortex tube (RHVT), and compressed air. Machining performance was investigated in terms of micro-hardness, tool tip temperature, tool wear, cutting forces, work surface roughness, chip morphology, and energy consumed. Results manifested that MQL and tool coatings can significantly lower tool tip temperature by up to 16%, tool wear by up to 102–106%, average cutting forces by 17–21%, and surface roughness reduced from 11–21% as compared to dry conditions.

涂层硬质合金刀具在不同可持续金属加工液策略下车削Al 7075-T6航空合金

摘要：我们主要需要减少金属加工液的消耗，以确保航空航天合金的可持续和环保加工。本研究旨在确定在不同的环保金属加工液策略下，即干式加工、最小量润滑（MQL）、Ranque-Hilsch涡流管（RHVT）和压缩空气下，用于航空航天铝合金（Al7075-T6）涂层硬质合金刀具可持续车削的各种环保金属加工流体策略的效率。从显微硬度、刀尖温度、刀具磨损、切削力、工作表面粗糙度、切屑形态和能耗等方面研究了加工性能。结果表明，与干燥条件相比，MQL和刀具涂层可以显著降低刀尖温度16%，刀具磨损102-106%，平均切削力17-21%，表面粗糙度从11-21%降低。缩写：BUE，组合边缘；CVD，化学气相沉积；CrN、氮化铬；DCR，配置芯片比率；DLC，类金刚石碳；DSPR，报废率；能谱仪；MF，金属加工液；MoS2、二硫化钼；MQL最小润滑量；PVD，物理气相沉积；朗克-希尔希涡流管；RPSR，回收零件废品率；RSPR，再制造废品率；SEM、扫描电子显微镜；SDSS，超双相不锈钢；TiAlN、氮化钛铝
