Hastelloy is categorized as difficult to cut superalloy widely used in aerospace, nuclear reactor components and chemical industry because of its magnificent strength and higher heat efficiency. Since, the machining of this material is quite difficult and hence suitable cooling systems are required to achieve sustainable manufacturing goals. The present investigation has been focused on the machining performance and sustainability assessment of turning Hastelloy C-276 in dry, flood and minimum quantity lubrication (MQL) environments. Taguchi L-9 array has been utilized to conduct and record the experimental output along with TOPSIS approach to evaluate the sustainability. The output responses viz. cutting forces, surface roughness, cutting temperature, energy consumption and carbon emission have been recorded at various levels of input variables. The experimental results revealed that MQL has minimized the cutting forces, surface roughness and temperature by margin of 20-38%. Likewise, energy expenditure and carbon emission was declined by 9-27% respectively compared to other conditions. Sustainability analysis explored best performance index during equal weightage criteria at 125 m/min, 0.246 and 0.8 mm doc under MQL. However, implementing assigned weightage system evaluated best condition for dry machining as 88 m/min and 0.246 mm/rev having same doc. SEM analysis of insert reported mainly abrasion and adhesion type of tool wear at all parametric range and machining conditions.
哈氏合金被归类为难切削高温合金，因其具有出色的强度和更高的热效率，广泛应用于航空航天、核反应堆部件和化学工业。由于这种材料的加工相当困难，因此需要合适的冷却系统来实现可持续制造目标。本研究聚焦于在干式、湿切削和微量润滑（MQL）环境下对哈氏合金C-276进行车削加工时的加工性能和可持续性评估。采用田口L-9阵列进行实验并记录实验结果，同时运用理想解法（TOPSIS）来评估可持续性。在不同水平的输入变量下记录了输出响应，即切削力、表面粗糙度、切削温度、能量消耗和碳排放。实验结果表明，MQL使切削力、表面粗糙度和温度降低了20%-38%。同样，与其他条件相比，能量消耗和碳排放分别下降了9%-27%至。可持续性分析表明，在MQL条件下，当切削速度为125 m/min、进给量为0.246 mm/rev、切削深度为0.8 mm时，在等权重标准下具有最佳性能指标。然而，采用指定权重系统评估得出，干式加工的最佳条件是切削速度为88 m/min、进给量为0.246 mm/rev，切削深度相同。对刀片的扫描电子显微镜（SEM）分析表明，在所有参数范围和加工条件下，刀具磨损主要为磨料磨损和粘着磨损。
