“…Especially the varying frequency of thermal period and the periodic effect of cutting force are similar. According to the research of Mort, tool thermal fatigue can be considered as material fatigue under corresponding periodic temperature (as shown in formula 4) [14][15][16]. Here, C is material constant.…”

In this paper, the machinability of surface is introduced, and it is obtained from the analysis that the main macroscopic factors of tool premature failure are forging defects. Through research on the mechanism and rule of heavy-duty turning tool fracture failure, the conclusion is obtained that dynamic load leads to tool fracture and breakage finally. The tool working state under dynamic load is analyzed similarly by finite element software, and the simulate result verifies accuracy of the conclusion. Finally, the critical time model of tool fracture under dynamic load is established and the prevention measures of tool premature failure are formulated, which provide reference for the improvement of production efficiency and tool breakage prediction.
