A novel cold air electrostatic minimum quantity lubrication (CAEMQL) technique for the machining of titanium alloys Ti–6Al–4 V

The milling of titanium alloys is usually associated with a high cutting temperature and severe tool wear. Therefore, flood cooling technologies have been conventionally employed to prolong the life improve quality machined surface. However, negative impact on environment waste disposal problems caused by vast quantity metalworking fluids used in process become significant. In this study, new machining method called “cold air electrostatic minimum lubrication (CAEMQL)” proposed for alloy Ti–6Al–4 V. performance CAEMQL was systematically assessed terms force, temperature, surface roughness, life, wear, chip morphology, using (MQL), (EMQL), cold (CAMQL) as benchmarks. It found that resulted improved critical heat flux steady-state transfer compared MQL, EMQL, CAMQL, which thus produced lower smaller better quality, less degree segmentation enhanced deformation under due its synergistic effect.
