了解刀屑界面温度对优化加工条件、提高加工性能、设计高性能材料具有重要意义。为了掌握刀具-芯片界面的温度分布，本研究设计了一种可转位刀片，在靠近切削刃的前刀面上内置了7对微型Cu/Ni热电偶。本文介绍了一种内置微热电偶的可转位刀片的性能。微热电偶各元件的厚度约为15 μm。采用有限元法进行非定常热传导分析的结果表明，安装微热电偶后的温差小于10 K或1.2%。通过改变切削速度，对铝合金进行了切削测温实验。研究结果表明，利用内置微热电偶的可转位刀片可以准确地掌握刀具-芯片界面的温度分布。
Knowing temperatures at the tool-chip interface is extremely important to optimize the machining condition and to improve the machining performance, furthermore to design high performance materials. In order to grasp the temperature distribution at the tool-chip interface, this study has devised an indexable insert with seven pairs of built-in micro Cu/Ni thermocouples on the rake face near the cutting edge. This paper shows the performance of the indexable insert with built-in micro thermocouples developed. The thickness of each element of the micro thermocouple is approximately 15 μm. The result of unsteady heat conduction analysis employing FEM shows that the temperature difference by installing the micro thermocouples is less than 10 K or 1.2 %. The temperature measurement experiments by cutting of aluminum alloy were carried out by changing the cutting speed. The results provided the evidence that the temperature distribution at the tool-chip interface can be grasped with the indexable insert with built-in micro thermocouples developed.
