EXPERIMENTAL AND SIMULATION ANALYSIS OF SPRINGBACK IN THECASE OF A DRAWN HALF-RIM MADE USING TOOLS CORRECTED BYAPPLYING THE TAGUCHI METHOD OF OPTIMIZATION
Springback of draw parts considerably affects their accuracy and deviations from the theoreticalprofile, this instability phenomenon determining the following changes of the part shape and geometricparameters: arching of the part sidewall, modification of the angle formed by the part bottom and thesidewall, modification of the angle between the flange and the sidewall. Hence, in order to obtain thedesired accuracy of the draw parts it is necessary the development of a method for the reduction or theelimination of the springback. The present paper presents the results of an experimental analysis ofspringback parameters resulted in the case of a draw half-rim manufactured by using tools corrected in thedesigning stage by applying the optimization Taguchi’s method.
