The Simulation and Experimental Study of Residual Stress Based on Thermo-Mechanical Model of GCr15

Abstract:

The metal machining 3D finite element model was established on the basis of the thermal-elastic-plastic finite element theory. And the machined surface residual stress simulation in different cutting parameters was obtained through the finite element analysis. It is concluded that the residual stress distribution variation is spoon-shaped curve. When the feed increased, the slope of the curves is smaller, however the speed increased, the slope of the curves is higher and the stress tends to negative values quicker. Finally, the experiments are carried out. The result was basically consistent with the simulation.
