An Alternate Method to Springback Compensation for Sheet Metal Forming
The aim of this work is to improve the accuracy of cold stamping product by accommodating springback. This is a numerical approach to improve the accuracy of springback analysis and die compensation process combining the displacement adjustment (DA) method and the spring forward (SF) algorithm. This alternate hybrid method (HM) is conducted by firstly employing DA method followed by the SF meth...
متن کاملTool Design for a High Strength Steel Side Impact Beam with Springback Compensation
Prediction of formability for sheet metal pressings has advanced to a high state of confidence in recent years. The major challenge is now to predict springback and, moreover, to assist in the design of tooling to correctly compensate for springback. This is particularly the case for materials now being routinely considered for automotive production, such as aluminium and ultra high strength st...
متن کاملdie shape design in channel forming process by compensation of springback error
shape error due to elastic recovery of formed part in unloading known as springback, is one of the most important problems of tool design in sheet metal forming processes. many researches have been performed for proposing an efficient method to decrease or compensate springback error in sheet forming processes. these methods are usually based on iterative finite element algorithms. in this pape...
متن کاملPossibilities and Strategies for Simulations and Compensation for Springback
Simulating the forming process for sheet metal parts is currently the standard for guaranteeing feasible manufacturing at the time of tool design. In contrast simulating springback and its computer-supported compensation is still under development. The status of the technology for simulating springback will be illustrated and demonstrated using examples. Various strategies related to compensati...
متن کاملRobust optimization strategies for sheet metal springback compensation
Sheet metal forming is a major industrial process, mainly due to its cost efficiency after the establishment of the process design. However, the process design from tools geometry to load conditions is not straightforward, as a consequence of the side effects associated with sheet metal forming. The emphasis in this area goes to the springback effect or elastic recovery, which is one of the mai...
