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...
متن کاملAn 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 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...
متن کاملNumerical 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...
متن کاملSpringback Effect Prediction in Wipe Bending Process of Sheet Metal: a Ga-ann Approach
Sheet metal is one of the most important semi-finished products used in automobiles, domestic appliances, aircraft and other familiar products. Therefore sheet metal forming technology is an important engineering discipline in the area of mechanical engineering. In sheet metal forming, wipe bending process plays a major role in which the sheet metal tries to return to its original shape after r...
