英文摘要：

With the infrared temperature measurement system on-line monitoring the dynamic change of the cutting temperature in the milling process of high-speed being monitored, the corresponding cutting temperature while machining with tools of the different wear degree and materials are presented, mean- while, the varying characteristic of the cutting tempera- ture with the cutting velocity, which are essential to the development of high-speed cutting aluminum and to the optimization of high-speed cutting process is put for-ward.
