Effects of Molybdenum disulfide nano-particles’ concentration on waste cooking oil nanofluid in reduction feed force in CNC wet machining of SAE 1144 steel

Used Cooking oil, which is typically discarded as garbage in vegetarian eateries, is put to good use in this study as a precursor to a unique nano fluid. Nano fluids can also be utilized as a lubricant in the machining of precision shafts. This study looked into how a fluid containing nanoparticles of molybdenum disulfide in used cooking oil can reduce feed forces. In this study, two groups of samples were used: group I consisted of items that had undergone green machining (turning) on a heavy-duty lathe, serving as a control group. The intervention group's sample was processed using a wet machining technique that relied on waste cooking oil supplemented with 0.3% Molybdenum disulfide Nano-particles, representing a clean technology approach. There were supposed to be 12 people in each group based on the G-Power 80% estimate, but in the end 16 people per group were considered for the tests. Material processing of SAE 1144 shaft by molybdenum disulfide enriched waste cooking oil based wet machining significantly reduced the Feed force compared to green machining and Molybdenum disulfide Nano-particles enriched waste cooking oil based wet machining method under a variety of input conditions with similar results. (p < 0.05) A value of p = 0.009 is considered statistically significant. Experimental results show that the feed force can be greatly reduced from 134.139375 N to 80.055625 N when using the suggested molybdenum disulfide enriched waste cooking oil-based wet machining technology to produce SAE 1144 shafts.
