Abstract : Cutting fluids are used in manufacturing processes to reduce friction, control heat generation, and extend tool life by providing heat absorption, lubrication, and cooling. Achieving higher productivity and quality in manufacturing is a significant challenge, with modern methods like CNC turning playing a critical role in addressing this challenge. The objective is to optimize CNC turning parameters specifically for machining EN19 alloy steel, which is widely utilized in automotive and machine tool industries. The goal is to enhance surface finish without sacrificing productivity. This requires strategic implementation of Dry machining, Minimum Quantity Lubricant (MQL), Flood Cooling, and Liquid Nitrogen Bath (LBN) techniques. Machining parameters such as cutting speed, feed rate, and depth of cut also play a crucial role in improving surface finish. Experimentation involves varying these parameters across different levels while applying all three lubrication conditions to determine their impact on surface finish. The most effective combination of machining parameters and lubrication methods can be identified through systematic testing and analysis to optimize surface finish while maintaining productivity in the CNC turning of EN19 alloy steel.

Keywords : CNC Lathe, Surface Finish, Talysurf, Parameters, Surface Roughness.
