Abstract The proposed work deals with the investigation of magnetorheological based minimum quantity lubrication of graphene oxide (GO) based jojoba oil as bio-lubricant on machinability and tool wear mechanism of turning Monel K500 alloy. Experiments were carried out for dry, flooded, minimum quantity lubrication (MQL) and magnetorheological (MR–MQL) conditions using medium duty lathe. The process parameters include the cutting speed 95, 110, 125 m/min, feed rate 0.050, 0.075, 0.1 mm/rev and depth of cut 0.25, 0.50, 0.75 mm for the output responses such as surface roughness, cutting temperature and tool flank wear. The results indicated that GO-based bio-lubricant MR–MQL reduced coefficient of friction (COF) of 0.051 and wetting angle of 6°, as well as improved machining performance such as cutting temperature of 145 °C, the surface roughness of 0.614 µm, flank wear of 0.18 mm with enhanced lubrication regime under extreme wear conditions.

磁流变微量润滑对蒙乃尔K500合金车削加工性、润湿性和摩擦学行为的影响

摘要 拟议的工作涉及基于磁流变学的最小量润滑石墨烯氧化物 (GO) 基荷荷巴油作为生物润滑剂对车削 Monel K500 合金的可加工性和刀具磨损机制的研究。使用中型车床在干式、满液式、微量润滑 (MQL) 和磁流变 (MR-MQL) 条件下进行实验。工艺参数包括切削速度 95、110、125 m/min、进给速率 0.050、0.075、0.1 mm/rev 和切削深度 0.25、0.50、0.75 mm，用于输出响应，如表面粗糙度、切削温度和刀具后刀面穿。结果表明，基于 GO 的生物润滑剂 MR-MQL 降低了 0.051 的摩擦系数 (COF) 和 6° 的润湿角，并提高了加工性能，例如切削温度为 145 °C，
