Cutting zone temperature reduction in by using novel nanofluid in SAE1144 machining

Abstract

CNC Lathe is generally utilized for motor shaft machining. The cost of machining is high as it is machined in CNC machining as well as high cutting speed employed whereas heat generation is more. High cutting zone temperature causes thermal defects in the products. This research focused to create novel nanofluids with the use of waste cooking oil and Molybdenum disulfide Nanoparticles for cutting fluid for machining the SAE 1144 steel shaft. Two independent groups with Taguchi L16 experimental design were employed in this research. This investigation aims to make a shift from CNC-based machining to conventional machining practices without compromising the quality requirements by the reduction of cutting zone temperature with the use of a Novel nanofluid to provide cooling and lubrication at the cutting zone. This study investigates the effect of Molybdenum disulfide Nanoparticles’ concentration on waste cooking oil (Nanofluid) to reduce Cutting zone temperature while machining SAE1144 shaft. The observations were statistically validated. The base fluid is waste cooking oils from the largest sweets and savouries manufacturer as well as a widespread hotel network source. Green machining principles are compared with the findings. The results pass the statistical threshold for validity. That is the proposed clean machining practices reduced the average cutting zone temperature from 271.06 °C (dry/ green machining) to 194.94 °C. A low concentration of 0.1% gives better results at low as well as high cutting speeds. The cutting zone temperature is highly influenced by cutting speed.
