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...

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...

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...

Feature Recognition and Design Advisory System for Sheet Metal Components

The present paper explains a feature recognition module and design advisor system for sheet metal components. In this system features of sheet metal components are extracted automatically from 3-D model. These data are modeled based on object oriented. The proposed system will aid the designer right at the design stage with useful design and manufacturability recommendations that have been gath...

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
