Abstract：

Billet shape of precision coining cube part is not rectangle in general.If the geometry parameter of the billet is not reasonable,some quality issues,such as failed filling or burr,might be found during processing.One method of billet shape definition for precision coining cube part was put forward and the mathematic model was set up by reverse calculation method.Parameters of the model were calculated by numerical simulation based on DEFORM-3D,velocity distribution and minimum distance distribution were analyzed.Reasonable geometry parameter of the billet was obtained,and it was verified by physical experiment.
