Abstract
The objective of this investigation is the forming of a flange with grooves similar to that of a V-belt pulley or a cogged-belt pulley by a new method of applying reverse redrawing. The first step of the survey is a finite element analysis of individual forming processes. Next, the relationship between experiment and simulation is examined in terms of the load-stroke curve and the shape of the product. This method is composed of four processes. The first process is deep drawing, the second process is compressing the end of the drawn cup, the third process is embossing to make a groove at the end of the cup, and the fourth process is forming a flange with grooves by reverse redrawing. Furthermore, each process is simulated, and the condition that makes possible, "formable area", can be attained.
