    Hi,

     

    spring back is function of your material properties. Make sure the material stress strain curve is same as the test material. also the strain hardness coeff (n) has to be same.

     

    for more accurate springback prediction use the constrains or SPC method instead of Automatic mode. this will also help you position the part while part coamprision.
