CONTROLLING THE WORKING AREA IN FLEXIBLE SHEET FORMING DIES

Abstract

Design and fabrication of a die, in the case of sheet metal forming, is an experimentally iterative process. So, the hard sheet metal forming dies are generally dispensed with flexible dies. This paper presents a simple approach to control the motion of the die pins and estimation of blank working area. The proposed method is directed to control any free form shapes such as Bezier surfaces. The results of the study are simulated in suitable programming code (MATLAB and IronCAD) to show the effect of proposed method.
