Finite element-based orthogonal cutting simulations were performed with titanium alloy TiAl6V4.The orthogonal cutting experiments were used to validate the numerical model.Based on the systemic simulation results,the dependences of strain,strain rate and temperature in the primary and secondary shear zone on the uncut chip thickness were investigated.The influences of material strengthening factors,including strain,strain rate and temperature effects,on the "size effect" in specific cutting energy were furt...
