摘　　要：金属切削过程中产生的切削热会影响刀具磨损、机床精度、材料去除机理、积屑瘤和工件的加工质量。在总结常用测温方法优缺点的基础上,重点综述了以薄膜热电偶为传感器的测温刀具。薄膜热电偶测温刀具不仅能够完成材料的切削加工,而且还可以原位监测刀—屑接触区的温度,为有限元法构建切削温度场提供数据支持,构建的切削温度场有利于刀具磨损过程和材料去除机理的研究。The cutting heat generated during metal cutting affects the tool wear,machine tool accuracy,material removal mechanism,chip accumulation and workpiece processing quality.This paper summarizes the advantages and disadvantages of common temperature measurement methods,and focuses on an overview of the temperature measurement tools with thin film thermocouples as sensors.Thin-film thermocouple temperature measuring tools can not only cut materials,but also monitor the temperature in the contact area between cutting tool and chip in situ,which provides data support for building the cutting temperature field by finite element method,and the cutting temperature field is beneficial to the research of tool wear process and material removal mechanism.
