“…al. have used a numerical model of MQL to simulate the liquid film formation for different milling tool velocities with inner channels and this study provided greater understanding of oil mist behavior [36]. The simulation of cutting fluids was also applied for drilling processes with twist drills.…”

“…The extreme reduction in lubricant quantities resulted in nearly dry workpieces and chips. Several studies highlighted the benefit of using inner channels in order to specifically spray the cutting area [1,[6][7][8][9][10]. This novel technique ensured precise lubrication supply directly to the cutting zone [11].…”

The main aim of this paper was to reproduce the frictional behaviour that occurred in milling with a pin-on-cylinder system. Three different tribological tests were conducted reproducing friction phenomenon that happened in three machining conditions: (i) dry rubbing, representing the dry machining condition, (ii) MQL applied to front face rubbing which was similar to milling with MQL applied on the insert rake face and (iii) MQL applied to rear end rubbing which was similar to milling with MQL applied on flank face. Tribological tests were carried out with coated tungsten carbide pins rubbing on X100CrMoV5 steel cylinder. Apparent coefficient of friction, adhesion area and heat flux transmitted to the pin were analysed. It has been shown that MQL rear end rubbing provided a lower adhesion area and lower apparent coefficient of friction than with MQL front face rubbing. Furthermore, MQL rear end rubbing resulted in a greater cooling ability. These findings helped to explain why better results were obtained with MQL flank face lubrication in milling compared to MQL rake face lubrication.

“…Finite element machining model has also been developed under the application of cryogenic cooling based on Johnson-Cook flow stress model and a constant convective heat transfer coefficient to account for the heat absorption by the cryogenic fluid. Duchosal et al [8] carried out modeling of machining under the application of minimum quantity lubrication (MQL) coolant process using an unsteady Reynolds-average Navier-Stokes (RANS) formulation. The model was used to simulate the liquid film formation using a multiphase Lagrangian model for the droplet-surface interaction process, while the heat transfer was ignored.…”

In this study, a heat transfer model of machining of Ti–6Al–4V under the application of atomization-based cutting fluid (ACF) spray coolant is developed to predict the temperature of the cutting tool. Owing to high tool temperature involved in machining of Ti–6Al–4V, the model considers film boiling as the major heat transfer phenomenon. In addition, the design parameters of the spray for effective cooling during machining are derived based on droplet–surface interaction model. Machining experiments are conducted and the temperatures are recorded using the inserted thermocouple technique. The experimental data are compared with the model predictions. The temperature field obtained is comparable to the experimental results, confirming that the model predicts tool temperature during machining with ACF spray cooling satisfactorily.
