Machining metals has been industriously expanding. The heat generated from the metal cutting process can hinder good results, such as machining performance or surface finish. The technology of minimizing the usage of cutting fluid, minimum quantity lubrication (MQL), has been achieved to move towards greener environments. To enhance the machining performance, MQL parameters need to be controlled. For the effect on the surface roughness, three factors are being adjusted: nozzle distance, nozzle angle, and MQL flow rate. The turning process employed with the MQL system has been conducted to attain the optimum MQL parameters using the Taguchi L9 orthogonal method. Aluminium Alloy 6061-T6 workpiece was selected to be the subject of the study. The results display the optimum MQL parameters to be 40 mm for the nozzle distance, 60° for the nozzle angle, and 54 mL/h for the flow rate. 3 more confirmation runs were conducted to replicate the ideal MQL parameters listed, and the results fell within the acceptable margin of error of 10%. Hence, this setup for obtaining the optimal surface finish can serve as a guide for future studies.
