Hot metal forming is one of the most important steps in manufacturing of a large variety of products. One of the oldest metal forming operations, drawing allows excellent surface finishes and closely controlled dimensions to be obtained in long products that have constant cross sections. Ironing in the deep drawing is done by adjusting the clearance between the punch and the rings and allowing the material to flow over the punch. In this study, the effects of process parameters on the ironing process were investigated numerically. The finite element analysis was verified with the measured load from the experiment. After validating of the finite element model, effects of preform temperature distribution, friction coefficient and eccentricity parameters on the force required for forming, the strength of the die and the geometry of the preform were investigated in detail. The present results clearly show that the proper selection of process parameters has a great effect on process outputs such as load, and ironed part geometry.
