In recent years, the use of innovative materials in high-performance applications has grown tremendously. Because of their poor machinability, these materials resolve a wide range of mechanical difficulties and need significant testing in milling. In the manufacturing business, machining is a fundamental and indispensable process. Cutting zone heat is essential for determining the quality of a work piece throughout the procedure of machining. In spite of fact that proper cutting fluids are employed in metalworking to dissipate heat, their use results in the destruction of nature and has an impact on the health of employees. Because the film layer arrangement reduces friction between the mating surfaces and therefore lowers the temperature, oil has an influence on the cutting zone, improving the surface finish in the process. Studies show that the presence of nanoparticles in cutting fluid reduces the cutting force and temperature, as well as improving the surface finish on the work piece’s surface. This results in increased throughput while reducing health risks and enhancing the preferred working conditions over the traditional minimum quantity lubrication (MQL) process. Despite being a popular solid lubricant, molybdenum disulfide (MoS₂) has the potential to be an efficient medium for MQL processing is studied. As a result, research is looking into ways MoS₂ nanoparticles affect machining variables, including surface polish, and cutting zone temperature. The ideal input parameters are chosen using Response Surface Methodology (RSM) through the Box – Behnken method. This paper presents high accuracy and is suitable for the machining process, The optimal R² value for the model is around 0.91, Hence the design is for surface roughness and R² as 0.9232 for temperature is obtained.
