A newly developed infrared radiation pyrometer equipped with two optical fibers is used to measure the cyclic temperature variation beneath the rake face of a cutting tool in end milling. A theoretical analysis is conducted using a semi-infinite rectangular corner model. In up milling, the temperature beneath the rake face increases gradually during the cutting period and reaches a maximum just after the cutting. In down milling, the temperature increases immediately after cutting starts ; it reaches a maximum and then begins to decrease during cutting. The temperature gradient toward the inner direction of the tool insert is about 300 degrees Celsius per 0. 5 mm. The effect of a cutting time on a tool wear is small

采用新研制的红外辐射高温计，用两根光纤测量了立铣刀前刀面下的循环温度变化。采用半无限矩形角模型进行了理论分析。在上铣削过程中，前刀面的温度在切削过程中逐渐升高，并在切削后达到最大值。下铣削时，切削开始后温度立即升高；在切削过程中达到最大值，然后开始减小。刀具内方向的温度梯度约为300摄氏度/ 0。5毫米。切削时间对刀具磨损的影响很小
