The modern manufacturing industry is characterized by reduced costs, high precision, and increased productivity. Tool life prediction and performance analysis of the machining process are thus essential in this industry. Cutting fluids play an important role in reducing friction, controlling temperature, increasing surface finish, and increasing tool life during machining processes. The research focuses on the effects of different cutting fluids conditions on surface finish, material removal rate, cutting temperature, and tool life. The dry machining, flood cooling, and Minimum Quantity Lubrication (MQL) techniques have been used in the comparative analysis. Carbide cutting tools are used for turning medium carbon steel materials. Taylor's Tool Life Equation and statistical analysis techniques have been used to analyze the behavior of tools as well as the machining process. As compared to dry and conventional flood cooling methods, the findings reveal that MQL provides a balanced combination of cooling and lubrication, thus increasing the life of tools and improving machining processes. The paper gives recommendations on how to select proper cutting fluid conditions for machining.
