中文摘要：

切削温度是影响切削加工过程中刀具状况和工件表面质量的重要物理量，但切削温度信号的获取与处理存在一些实际问题。针对切削温度测量中的自然热电偶法、人工热电偶法以及红外热图像法，介绍了热电偶的固定、从旋转体上引出测量信号、自然热电偶的标定、工件和刀具表面发射率的标定，以及应用红外热像仪进行测温时切削实验的设计等一些实践做法。实践证明，开槽嵌夹绞丝热电偶方法的测量结果比较可靠；采用集流器引出旋转体热电势信号时所产生的摩擦附加电势可被定量测定并可将其从测温信号中减除；应用红外热像仪测量切削温度时应标定被测材料在各温度段的表面发射率并量化标定环境的影响。

英文摘要：

There are some practical problems in the cutting temperature measurement applications such as how to set and fix artificial thermal couples in measured tool or workpiece, how to conduct the measurement signals in spinning bodies out and calibrate the correlations between temperatures and the thermal couples＇ heat potentials, how to design the cutting experiment condition and calibrate the materials＇ surface emissivity etc. This paper discussed these problems and introduced some experimental methods for the signal acquiring and processing in cutting temperature measurement. The experimental results prove： using the measurement method parting the tool or workpiece and inserting the thermal couples which have wringed ends can get credible data; when using current gatherer to conduct spinning body＇ measurement signal out, the frictional potential need to be distinguished and deducted; when using infrared imager to measure cutting temperature, the surface emissivities of tool and workpiese in various temperature ranges should be calibrated and the surrounding influence should be considered.
