Tool with Heavy-Duty Machining Tube Section of the Fatigue Analysis

Abstract

Because the tube festivals surface is not round, uneven, so the cutting tool is under impact unceasingly in cutting process. Cutting tool is extremely easy to have fatigue failure, therefore it is very necessary to use finite element numerical analysis software ANSYS to carry on numerical simulation analysis for heavy lathe tool intensity static. The force of cutting tool and distributed rule of definite cutting tool internal stress strain could be precisely got by using FEM, thus the analysis results could improve cutting tool stress condition and the structural design provides the theory basis

Research on the Tools’ Life in the Dynamic Heavy-Duty Cutting Process

“…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.…”
