The impact of different shapes of thread section on inverse identification while cutting the thread

In order to study the impact of different shapes of thread section on inverse identification, the technique of parameter inverse identification based model contrast methodology was conducted in this paper, and the thread material parameters of rectangle section was identified, and then this set of parameters was adopted in finite element model with thread section shape of triangle, zigzag and trapezoid for simulation computation respectively. After comparing the simulation results to their validation model, the material parameters was re-identified for each thread section shape, thus obtain the inner patterns how the section shape affect the inverse identification.
