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 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 کاملAn 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 کاملOptimization 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 ...
