According to the feature of the deformation zone in ring gear gag precision blanking,the effect of hydrostatics stress on metal plastic is analyzed in the theory.At the same time,the relation of hydrostatic pressure to dentation angle is proved by the method of extremum and slipping field.The results of the two approaches are accordant,which provides various methods on energetic analysis of precision blanking deformation zone.
