The hunt for environmentally friendly cutting fluids is underway as the problems of conventional become more evident. To achieve conscious machining, current study examines use Mango Kernel Seed Oil (MKSO) a fluid during turning AISI 1525 steel. According to 24 complete factorial techniques, vegetable-oil-based was produced by dissolving four different additives in mango kernel seed oil: emulsi...

Cutting fluids have a known negative impact on productivity, human health, and the environment in manufacturing sector. A suitable method for reducing effect of cutting health is minimum quantity lubrication (MQL). In this experiment, AISI 1039 steel was machined using vegetable oil lubricant MQL. chemical used to extract from palm kernel seeds. Then, established techniques, physicochemical lub...
