In order to get exact shape and size of components in sheet metal manufacturing, springback effect plays a pivotal role. Prediction of springback angle helps in determining the amount of over-bend (i.e. springback compensation) required so that exact V bend angle can be obtained in the component. In this study an attempt has been done to analyze the springback effect for simple V-bending operation performed on CRDQ (Cold Rolled Draw Quality) with thickness of sheet varying from 2.0 to 4.0 mm. In this work Hyperform software is used for simulating the springback effect in V bending operation. The main objective is to get the variation of amount of springback for different thickness of sheets keeping bending angle (60 0) and punch radius (2mm) constant. The results showed that the value of springback decreases with the increase in sheet thickness (from 2 mm) up till 3.3 mm. Further increase in sheet thickness, from 3.3 mm to 4.0 mm, increases the amount of springback for V-bending of CRDQ sheet. Thus, it is concluded that optimum sheet thickness to encounter minimum springback for CRDQ sheet is 3.3 mm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
