Hydroforming is a convenient method for applying fluid to produce parts with high strength to weight ratio. Hydrodynamic deep drawing assisted by radial pressure with inward flowing liquid process is considered as a type of hydroforming. In this method, radial and cavity pressures are two most important parameters, the values of which at any moment play an important role on the quality of final part. In this study, based on a hybrid method, the cavity and radial pressure paths in hydrodynamic deep drawing assisted by radial pressure with inward flowing liquid process are optimized. In this method, an adaptive simulation that is integrated with the fuzzy control system with the ABC algorithm is used to determine the optimized radial and cavity pressure paths. The achievement of a cup with least thinning and without wrinkling has been defined as the optimization goal. The validity of radial and cavity pressure paths obtained from optimization algorithm is verified through an experiment. Results showed that utilization of the optimized loading path yields the part with lower maximum thinning and without wrinkling.
