In a previous paper, it was shown that the temperature played a very significant role in the wear of cutting tool at the ultra high speed. It seems that a point of wide difference between the ultra high speed cutting and conventional cutting is the temperature distribution in shear zone.
This experiment was made to analyze the effects of the temperature distribution on the configuration of tool wear. High speed steel tool and 60-40brass (work material) were used in the test under different cutting conditions at speed range of 1000-7000m/min.
As the results, in the ultra high speed cutting, it was found that the effect of tool face temperature on end face was very small, and the configuration of tool wear was significantly influenced by temperature distribution on shear plane.
