Abstract：

The plastic deformation of forgings is greater than elastic deformation in forging, and the springback after the deformation of the forging is ignored , but as the precision forging technology development, researching on geometry precision error of workpiece and predicting springback has become a problem to be solved for the precision forging process. The research history of springback was reviewed，according to analytical method，experimental measurement and numerical simulation，the research situation,the existing problems and achievements of the springback of precision forging at home and abroad were comprehensively discussed,which had an important reference value for the research of precision forging springback .
