本文研究了切削刀具内置热管对切削温度和切削磨损的影响。刀具的温度对热变形和加工零件的尺寸精度以及加工中的刀具寿命起着重要作用。提出了一种新型的嵌入式热管技术，可以有效地去除切削过程中刀-屑界面产生的热量，从而减少刀具磨损，延长刀具寿命。特别是，该技术可以有效地减少由切削液引起的环境污染和污染，以及制造过程中皮肤暴露和颗粒吸入的健康问题。ANSYS有限元分析模拟表明，在切削过程中，嵌入热管的切削刃附近的温度显着下降。在切削刀具刀片上的几个位置处的温度测量结果与有和没有热管的模拟结果一致。实验进行了表征的温度分布时，执行车削实验，使用安装有嵌入式热管的切削刀具。热管降低切削刀具温度的性能进一步得到了切削刀具材料颜色、切屑颜色和切屑曲率半径的观察结果的支持。
This paper investigates the performance of a cutting tool embedded with a heat pipe on reducing cutting temperature and wear in machining. The temperature of a tool plays an important role in thermal distortion and the machined part's dimensional accuracy, as well as the tool life in machining. A new embedded heat pipe technology has been developed to effectively remove the heat generated at the tool-chip interface in machining, thereby, reducing tool wear and prolonging tool life. In particular, the technique can effectively minimize pollution and contamination of the environment caused by cutting fluids, and the health problems of skin exposure and particulate inhalation in manufacturing. The ANSYS finite element analysis simulations show that the temperature near the cutting edge drops significantly with an embedded heat pipe during machining. Temperature measurements at several locations on the cutting tool insert agree with the simulation results both with and without the heat pipe. Experiments were carried out to characterize the temperature distributions when performing turning experiments using a cutting tool installed with an embedded heat pipe. The performance of the heat pipe on reducing the cutting tool temperature was further supported by the observations of cutting tool material color, chip color, and the chip radius of curvature.
