Abstract：

In order to predict the elastic-plastic changes and the wire forming law of metallic wire in bending process accurately, the finite element simulation of wire bending process was done by using Deform，and the conclusion that the rolled angle of the wheel presented a linear relationship with the final wire forming angle within a certain range was derived. It has been proved to be truth by CNC wire bending machine test under certain conditions. And the empirical formula derived with fitting method was used to give processing compensation.
