Investigation of Effective Parameters of Spring-Back in CK67 Steel Sheet Metal Using Finite Element Method

Abstract:

Accurate prediction and controlling of spring-back within acceptable tolerance limits is absolutely essential for the design of bending die in order to produce sheet metal parts. This phenomenon which is defined as elastic recovery during unloading is one of the most important factors to influence the quality of sheet metal forming. This paper presents a study of spring-back in V-bending process of an isotropic CK67 steel sheet. In this investigation, in order to study the effects of significant parameters on spring-back, numerous simulations are performed using Finite Element Method (FEM). A two dimensional finite element model is developed using ABAQUS/Explicit intending to carry out a comprehensive study and prognosticate spring-back with variable parameters including punch load, punch tip radius (R _p) and thickness. Numerical results obtained from the simulations are discussed in details in several diagrams. These results represent verifiable and practical data that are in line with the results of previous researchers.
