Because the influence of temperature to tool area, work material performance's variety and the machined surface's quality, the research to temperature field in metal cutting is very important.
由于切削时的温度场对刀具磨损的部位、工件材料性能的变化、已加工表面质量都有很大的影响，因而对温度场的研究也显得尤为重要。
In the case of UMT, as cutting process has occurred in the local area adjacent to the tool tip, the wear mechanism must differentiate with macroscopic world.
在超精密加工中，切削过程仅仅发生在刀尖局部微观区域，刀具的磨损规律必然与宏观条件下有很大不同。
