Abstract

Present study describes the approach of applying MULTI-OBJECTIVE OPTIMIZATION method to optimizing of SHEET METAL FORMING Die. In many studies, Finite element analysis and optimization technique have been integrated to solve the optimal process parameters of SHEET METAL FORMING by transforming multi-objective problem into a single-objective problem. This paper aims to minimize the objective functions of fracture and wrinkle simultaneously. Design variables are blank-holding force and draw-bead geometry. RESPONSE SURFACE MODEL has been used for design of experiment and finding relationships between variables and objective functions. In designing of experiments v-optimal design has been used which minimizes the average prediction error variance, to obtain accurate predictions. Forming Limit Curve has been used to define the objective functions. Finite element analysis applied for simulating the forming process. Proposed approach has been investigated on a drawing part and experimentally verified. The optimal design showed a good agreement with experimental species. It has been observed that proposed approach provides aneffective solution to design of process parameters without a the ‘trial and error’ procedure.
