This innovative experimental work compares the machining performance of cryogenic machining using LCO₂ and LN₂ with conventional mineral-based flood machining for drilling Ti-6Al-4V to establish a sustainable cutting fluid strategy. In this context, machining performance indicators like surface roughness in R_a, Active Cutting Energy (ACE), Active Energy Consumed by Machine Tool (AECMT), and Energy Efficiency (EE) have been analyzed for each three cutting conditions. Also, ReCiPe midpoint 2016 (H) has been employed to perform LCA examination and measure the impact of drilling Ti-6Al-4V on natural resources, human health, and ecosystem. The range for the values of R_a has been found as 0.6–0.78 μm, 0.56–0.72 μm, and 0.75–0.8 μm for flood, LCO₂, and LN₂ as cutting fluids respectively when the cutting speed and feed rate are 80 m/min and 100 mm/min respectively. The increased values of ACE and AECMT with lesser values of EE have been found for flood machining in comparison with cryogenic machining. The results of LCA suggest that 67–99% of the whole impacts on ecology due to three cutting conditions are generated by flood machining only. Thus, cryogenic machining using LCO₂ and LN₂ has been emerged as sustainable cutting fluid strategies as a substitute for polluted mineral-based flood coolant.

这项创新的实验工作比较了使用 LCO ₂和 LN ₂的低温加工与用于钻探 Ti-6Al-4V 的常规矿物基洪水加工的加工性能，以建立可持续的切削液策略。在此背景下，已针对每三种切削条件分析了加工性能指标，例如R _{a 中的}表面粗糙度、有效切削能量 ( ACE )、机床消耗的有效能量 ( AECMT ) 和能源效率 ( EE )。此外，ReCiPe midpoint 2016 (H) 已被用于执行 LCA 检查并测量钻孔 Ti-6Al-4V 对自然资源、人类健康和生态系统的影响。值的范围ř_一个已被发现为0.6-0.78微米，0.56-0.72微米，0.75-0.8微米洪水，LCO ₂和LN ₂分别作为切削液时，切削速度和进给速度为80米/分钟和100毫米/分钟分别。与低温加工相比，水浸加工的ACE和AECMT值增加，EE值较小。LCA 的结果表明，三种切削条件对生态的整体影响的 67-99% 仅由洪水加工产生。因此，使用 LCO ₂和 LN _{2 的}低温加工已成为可持续的切削液策略，可替代受污染的矿物基溢流冷却剂。
