Cutting fluids are used in machining processes to reduce friction and heat on contact surfaces, and to increase the tool life and the quality of machined surfaces. An ideal lubricant should be the least toxic, least expensive, and least harmful to the environment. Additionally, it should possess good lubrication properties, resistance to low temperatures, recyclability, as well as thermal, oxidative, and hydrolytic stability. Moreover, its viscosity should be within an optimal range, neither too high nor too low. Selecting the optimal cutting fluid for the machining process is crucial, considering the desired characteristics of the cutting fluids. This study discusses five different cutting fluids commonly used in machining processes: canola oil, TMPTO (trimethylolpropane trioleate), synthetic ester, PAG (polyalkylene glycol), mineral oil. The optimal selection of these cutting fluids was determined using multi criteria decision making (MCDM) methods, based on criteria such as toxicity, lubrication ability, oxidative stability, thermal stability, hydrolytic stability, viscosity index, low temperature, and cost. The most widely used methods TOPSIS, VIKOR, MOORA, and as well as the recent RIM methods, were employed. The rankings obtained from the methods were established, and correlations between the methods were examined through Pearson correlation tests. The strongest correlation (coefficient: 0.923) was found between the MOORA and VIKOR methods. By analyzing the correlation coefficients and the ranking values, a clear ranking was determined. According to this clarified ranking, it was concluded that the PAG cutting fluid ranked first, synthetic ester ranked second place, and vegetable-based canola oil ranked last.
