Sheet Metal Forming: Springback Control

I. Springback control and active control of spring backsheets Sheet metal forming requires extensive technical knowledge, manufacturing application standards, and interactions between processing and material properties. One of the main reasons for parts mismatch is spring back. This is defined by Hu, Marciniack and Duncan as elastic strain recovery of the material after removal of the mold (2002). In this paper, we will explain experiments by Vikram Viswanathan (Northwestern University), Brad Kinsey (New Hampshire University), Jian Cao (Northwestern University) called "Experimental Implementation of Neural Network Rebound Control".

Sheet metal forming has existed for centuries. Today, traditional and more modern sheet metal forming methods are used in the automotive industry. Most metal forming processes are currently done by computer controlled machines. This enables you to quickly and reliably create automobile parts. There are various ways to deform the metal plate. This process is one of the oldest sheet metal processing. Traditional forging methods are metals that are usually struck by blacksmiths. Most of today's work is done by a machine like Drop-Hammer that works in the same way as past blacksmiths. This process is usually accomplished by preheating to a specific temperature before processing. Forging at the moment can be carried out under warm or cold conditions to achieve an appropriate balance of force, ductility and end product performance.

Because electromagnetic forming is highly controllable, it is very suitable for automation. Electromagnetic molding has a better tolerance level and the bouncing in the object is significantly smaller than the spring back in the mechanically shaped object. The current problem with this technology is that it can not produce large sheet metal parts due to design constraints. Most metal processing uses traditional molds and presses. Sheet metal processing is divided into two types on a printing press, not on a printing machine. Stretching, rotating and high speed forming are processes that do not use press. However, punching, stretching and shearing use a press. A press can be classified as a machine that changes the shape of a workpiece
