Research on Springback Compensation in Age Forming

The application of springback compensation to the CAD

To compensate for springback after forming,the tools have to be modified.This turns out to be a complicated and time consuming task.Also,because the surface description is generally not flexible enough,the springback compensation cannot be transferred to the CAD geometry entirely,and the accuracy of the compensation is heavily reduced.Springback in stringer sheet stretch forming - ScienceDirectJan 01,2013 Research on Springback Compensation in Age Forming#0183;Numerous investigations aim at influencing the springback behaviour in sheet metal forming.Schmoeckel and Beth found that there is little to no influence of the blank holder pressure curve on springback in a draw-bending process .Yan and Ruan investigated different methods of die adjustment for the compensation of springback .Springback in stringer sheet stretch forming - ScienceDirectJan 01,2013 Research on Springback Compensation in Age Forming#0183;Numerous investigations aim at influencing the springback behaviour in sheet metal forming.Schmoeckel and Beth found that there is little to no influence of the blank holder pressure curve on springback in a draw-bending process .Yan and Ruan investigated different methods of die adjustment for the compensation of springback .
