Abstract: (1344 Views)
In this article, the improved Oxley model, which is actually a combination of the Oxley and Johnson-Cook models, was introduced. The Oxley model does not take into account the effects of strain rate, hardness and heat increase, so by linking the Johnson-Cook model with this model, the Oxley model was developed. In this article, a program was written with Matlab software, which performed the analytical solution of the drilling process with the improved Oxley model, and according to the classical torque formula, the amount of this parameter was calculated according to the tangential force output from the Matlab code. Then the value of torque was compared with the value of this parameter in numerical modeling using AdvantEdge software, The difference between the numerical and analytical solutions is 12.5%, which indicates that the approximation in the presented analytical model is acceptable.
