The Influence of Phosphate-Ester-Based Additives on Metal Cutting Fluid Behavior during the Machining of Titanium Alloy

The behavior of four phosphate ester additives with varying levels phosphorus concentrations (very high, medium, and low) was examined through the course drilling a Ti-6Al-4V titanium alloy at constant metal removal rate (4.2 mm3/s). Cutting fluid (CF) were evaluated using torque, specific cutting energy (SEC), tool wear. conditions employed had significant influence on performance additives. At 0.105 m/s 0.188 m/s, very high phosphorous possessed lowest SCE torque values. high-phosphorous-level displayed enhanced 0.293 m/s. 0.419 medium-phosphorous-level preferable. esters observed to be related working mechanisms additives, which, in turn, associated formation phosphorus-rich tribolayer an organophosphate blade.
