CIRP Annals - Manufacturing Technology 54 (1) : 71-74. ScholarBank@NUS Repository. | Abstract: | In this paper, the Johnson-Cook (JC) strength model is used to describe the flow stress of Ti6Al4V and to estimate two important parameters in Oxley's model: the strain-rate constant and the angle made by the resultant force and the shear plane. The JC model is also incorporated into a finite element method (FEM) simulation for the deformation process of Ti6AI4V. Finally, a hybrid cutting force model based on the FEM simulation and Oxley's theory is proposed to predict cutting forces when machining Ti6Al4V. Experimental results are found to substantiate the developed model. | Source Title: | CIRP Annals - Manufacturing Technology | URI: | http://scholarbank.nus.edu.sg/handle/10635/54262 | ISSN: | 00078506 |
