在这项研究中，加工Ti-6Al-4V下的应用雾化切削液（ACF）喷雾冷却剂的热传递模型的开发预测的切削刀具的温度。由于Ti-6Al-4V切削过程中刀具温度较高，模型将薄膜沸腾视为主要的传热现象。基于液滴与工件表面相互作用模型，推导出了有效冷却的喷雾设计参数。进行了切削实验，并使用插入热电偶技术记录温度。实验数据与模型预测进行了比较。所得到的温度场与实验结果相当，证实了该模型预测的ACF喷雾冷却加工过程中的刀具温度令人满意。
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.
