Abstract

Wall-ironing is a metal forming process to reduce the wall thickness and increase the cup length. Ironing is a bulk forming process where the deformation force (tensile force) must be absorbed by the cup wall which is deformed. In the ironing process, the thickness reduction ratio or TRR is an important factor. If TRR is low to achieve the desired thickness, the process should be carried out several times. The greater the TRR, the more increased tensile force resulting in a larger stress. If the stress in the formed cup wall exceeds the tensile strength of the cup material, the base is torn off. This stress must be between the yield and the ultimate stress of the material. The die angle also affects the ironing force. This research is using CATIA software in order to get the die angle, TRR, and ironing force relationship.In this study, the products used are deep-drawn aluminum cup 37 mm of outer-diameter, 32 mm inner-diameter …
