Numerical study of heat transfer aspects in cutting tools made of Al2O3, ZrB2, TiB2, TiN using ANSYS fluent software
(2022) Mohammed, Kamal; Baştürk, Süleyman
In this study, the effects of heat transfer and heat flux on cutting tools with materials of Al2O3, ZrB2, TiB2, TiN are investigated numerically by ANSYS fluent software. The numerical model was validated with the previous study. The influence of the machining parameters such as cutting speed and feed rate on the temperature and tool life has been investigated to indicate the optimum cutting tool and situation. The results show that Zirconium diboride (ZrB2) and Titanium diboride (TiB2) have a temperature less than the aluminum oxide (Al2O3) so that the productivity will increase with the diboride materials utilizing as cutting tool. The maximum temperature for aluminum oxide is 1300 K while the Titanium Nitrite achieved 1100 K. The lowest and maximum temperature was measured at a cutting speed of 180 m/min and 220 m/min, respectively. The optimum cutting condition has been obtained with TiN cutting tool material at 180 m/min cutting speed and 0.138 mm/ rev feed rate. Titanium diboride (TiB2) materials achieved the maximum cutting tool life comparing to other materials.
