An Alternate Method to Springback Compensation for Sheet Metal Forming

Robust 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...

Possibilities 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...

Numerical and Experimental Investigations on Springback of U-bending of DP600 Steel Alloy Sheet

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...

An Experimental Study of Springback of Bent Sheet Metal Parts

Bending is the uniform straining of material around a straight axis and is used commonly in various sheet metal industrial products. Since all materials have a finite modulus of elasticity, plastic deformation is followed by some elastic recovery when the load is removed. In bending processes this phenomenon is called springback. Springback occurs not only in flat sheets or plate, but also in b...

Springback is very important factor to influence quality of sheet metal forming. Accurate prediction and controlling of springback is essential for the design of tools for sheet metal forming, many parameters
