Optimum blank shape design in deep drawing process using a new boundary updating formula
Source abstract
Abstract
Blank design is an important task in sheet metal forming process optimization. The initial blank shape has direct effect on improving the part quality, reducing the cost of production, time, waste and improve the thickness distribution in the production part. This paper presents a new iteration based method for optimizing the shape of a blank in the deep drawing process. Also three other iteration based algorithms reported in the literature are described briefly. The optimum blank shapes for some case studies are obtained using each algorithm and the results are compared. The general solution to optimum blank design is use numerical simulation iterative based methods. The present study implements a similar approach and presents a new algorithm to make geometrical corrections to the external boundaries of a blank in several iterations. In this paper, numerical simulation of the deep drawing process based on the finite element method is performed using Abaqus software and a computer program was developed to automatically run these iterations to study the features of the proposed method. The results indicate that the algorithm developed in the current work is more efficient.
