热管辅助刀具散热是一种新型的金属切削冷却方法。然而，作为评价冷却性能的一个重要指标，热管切割机在切割过程中的热分配在以前的文献中还没有报道。本研究主要是针对热导管切割机所产生的热量以及热导管所散发的热量进行估算。目的是表征热管刀具的热分配，从而评价其冷却性能。本文给出了正交切削时刀具上可触及位置温度测量的实验结果。利用测得的温度数据，采用有限差分法和逆过程求解了加载在刀-屑界面上的热流密度和流入热管刀具各部分的热量。结果表明，热管的安装增加了流入工具的热量，然而，更多的热量可以通过热管耗散，这导致在工具-芯片界面处的温度降低。
Dissipation of the cutting heat through the cutting tool assisted by the heat pipe is a new cooling method in metal cutting. However, as an important indicator to evaluate the cooling performance, the heat partition in the cutting process for the heat pipe cutter has not been reported in the previous publications. This investigation is concerned with the estimation of the amount of heat flowing into the heat pipe cutter and that dissipated by the heat pipe. The aim is to characterize the heat partition of the heat pipe cutter and thus evaluate its cooling performance. Experimental results are presented of temperature measurements at the accessible positions on the cutter during orthogonal cutting. With these measured temperatures, the finite different methods and an inverse procedure are utilized to solve the heat flux loaded on the tool–chip interface and the amount of heat flowing into each part of the heat pipe cutter. It is shown that the installation of the heat pipe increases the heat flowing into the tool; however, much greater amount of heat can be dissipated by the heat pipe; this results in the reduction of the temperature at tool–chip interface.
