Optimization of Sheet Forming Process for the Reduction of Springback
The introduction on large scale of high strength materials in automotive industry provided the possibility to reduce weight and produce safer cars. But at the same time these materials yield more springback than deep drawing steels. This can lead to problems designing the right tools for the forming process. This paper presents a method for the optimization of sheet metal forming parameters in ...
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...

Using Neural Network for Springback Minimization in a Channel Forming Process
Springback, the geometric difference between the loaded and unloaded configurations, is affected by many factors, such as material properties, sheet thickness, lubrication conditions, tooling geometry and processing parameters. It is extremely difficult to develop an analytical model for springback control including all these factors. The proposed neural network model is an attempt to deal with...
