Investigating concentration of nano-particles influence in Molybdenum disulfide waste cooking oil nanofluid for machining of SAE 1144 in surface finish enhancement

When a shaft breaks under fatigue, the condition of its surface is crucial. The precise shafts used in this application are machined using used cooking oil or waste cooking oil from a Kerala chips store. This study looks into how a Nano fluid containing Molybdenum disulfide Nano-particles enriched in used cooking oil can reduce the surface roughness of a material. In this study, two groups of samples were used: one group had their samples machined (turned) using a green machining method on a heavy-duty lathe, and the other group had their samples machined using a wet machining method that took a clean technology approach by varying the concentration of Molybdenum disulfide Nano-particles in waste cooking oil. It was determined that 12 people each group would be needed to run reliable studies with a G-Power of 80%, but 16 people per group were seriously evaluated. Material processing of SAE 1144 shaft by graphite enriched waste cooking oil based wet machining method significantly decreased Surface Roughness when compared to green machining and Molybdenum disulfide Nano-particles enriched waste cooking oil based wet machining method under similar input conditions. The condition of p < 0.05 indicates a significant value of 0.012. The experimental results show that the use of proposed Molybdenum disulfide greatly reduced the average surface roughness from 9.216875 µm to 1.3825 µm. Nano-particles enriched waste cooking oil based wet machining method, and the results do not contradict the statistical assumption. This method is therefore recommended for processing the SAE 1144 material for shaft manufacturing.
