N2 - Tool life has been a vital issue in machining titanium alloys. Recently, an atomization-based cutting fluid (ACF) application has been found to be an effective approach for cooling and lubrication in micro-machining operations. In this study, an ACF spray system is developed for macro-scale turning of Ti-6A1-4V. The spray system is designed to minimize interaction between the fluid droplets, and the gas nozzle to control the divergence of the fluid droplets. Experiments are conducted to study the effect of five specific ACF spray parameters including fluid flow rate, spray distance, impingement angle, and type and pressure level of the mist carrier gas on tool life, friction coefficient, and chip characteristics. It has been observed that the combination of low pressure (150 psi) air-mixed CO2 with a high flow rate (20 ml/min) produces a significantly longer tool life and broken chips. The results also reveal that the ACF spray system can extend tool life up to 40-50% over flood cooling.
