A compound die set for a blanking, drawing and punching operations are in many cases is very complex and expensive device. It is time consuming design die set by combining these three operations manually. This paper presents a Computer assisted design method to design compound die set for downlight housing. The design calculations take account of the quality of the workpiece material and they determine the optimal size for the die punch sets. The proposed method can be used for any
