摘要： 针对传统切削温度测量手段无法实时测量刀尖切削区域瞬态温度的技术难题，研制一种基于NiCr-NiSi薄膜热电偶的瞬态切削用智能测温刀具，采用直流脉冲磁控溅射技术制备了致密性和绝缘效果良好的SiO₂绝缘薄膜及热电偶电极薄膜；利用自行研制的薄膜热电偶自动标定系统对研制的测温刀片的静、动态技术特性进行测试和分析，结果表明所研制的测温刀片在30～300℃范围内具有良好的线性，其塞贝克系数为40.5 μV/K，最大线性误差不超过0.92%，且响应速度快，时间常数为0.083 ms；可嵌入刀杆的温度测试单元实现了在切削加工过程中对瞬态切削温度数据的实时采集、数据存储与无线传输功能；现场试验结果显示，所研制的智能测温刀具可以快速准确监测0.1 s内刀具刀尖处瞬态切削温度的变化，为瞬态切削温度测试提供了新的方法，为智能测温刀具的研究与开发提供了新的技术途径。

Abstract: For the technical problem that tool nose cutting area transient temperature can hardly be measured in real-time by traditional cutting temperature measurement method. In order to measure the transient temperature of cutting tip, the NiCr-NiSi film thermocouple is integrated on the cutting tool. By this way, an intelligent cutting tool is successfully developed, which can measure the transient temperature of cutting tip. The dense insulation SiO₂ film is deposited on the surface of cutting tool by pulsed DC magnetron sputtering technique. Then NiCr-NiSi film thermocouple is deposited on SiO₂ films. Finally, another SiO₂ film is deposited on the NiCr-NiSi film thermocouple. The static and dynamic calibrations of NiCr-NiSi film thermocouple are carried out in the self-developed automatic calibration system. Seebeck coefficient is 40.5 μV/K. The maximum linearity error and fast response time are less than 0.92% and 0.083 ms, respectively. The electronic measure unit embedded in the cutter bar can realize the function of real-time temperature acquisition, wireless transmission data, and/or data storage in the cutting process. Through the field experiment, the cutting tool with intelligent transient temperature measuring system can quickly and accurately detect the change of transient cutting temperature within 0.1 s, which provides new methods for transient cutting temperature measurement and the research and development of smart temperature measurement tool.
