Fig. 8 – The temperature distribution in the cutting zone.
In the FEM software AdvantEdge TM , the Johnson-Cook constitutive model
were used to predict the thermal behaviour in longitudinal turning process [1].
This software allows the temperature distribution, cutting forces and von
Misses stress to be predicted to appropriate measurements [2].
