三、切削热和温度场的研究随着现代加工技术和加工理论的发展,如自动化的发展,要求正确地估算刀具的寿命,而刀具寿命又与切削温度及其在刀具和工件中的分布密切相关,因此,如何提高对切削温度的预测和实验测量的精度,一直是金属切削研究的重要课题,不少学者对此作出了贡献。1980年,英国Harris,A.等研制了在工业闭路电视部件基础上的红外温度记录系统,如图1所示。使用光电摄象管,通过切削时发射的幅射能而使刀具和工件成象,将获得的电
Third, cutting heat and temperature field With the development of modern processing technology and machining theory, such as the development of automation, requires a correct estimate of tool life, and tool life and cutting temperature and its distribution in the tool and the workpiece close Therefore, how to improve the prediction of cutting temperature and the accuracy of experimental measurement has always been an important issue in metal cutting research, and many scholars have contributed to this. In 1980, the United Kingdom Harris, A. et al. Developed an infrared temperature recording system based on industrial CCTV components, as shown in FIG. 1. Using a photo tube, the tool and the workpiece are imaged by the radiant energy emitted during cutting, the electricity
