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

采用一种新研制的双光纤红外辐射高温计测量了立铣刀前刀面下的循环温度变化。采用半无限矩形拐角模型进行了理论分析。逆铣时，前刀面下的温度在切削过程中逐渐升高，在切削结束后达到最大值。在向下铣削中，切削开始后温度立即升高;它达到最大值，然后在切削过程中开始下降。朝向工具插入件的内部方向的温度梯度为约300摄氏度/0。5 mm。切削时间对刀具磨损的影响很小
