Simulation Study of Warm Deep Drawing Process Using AFDEX Software

Deep drawing is one of the most widely used metal forming process to produce sheet metal parts especially in automobile industries. Warm working is the plastic deformation of metal at temperatures below the temperature range for recrystallization and above the room temperature. This project aims to study the behaviour of the material AZ31B under warm conditions. This project also aims to optimize the process parameters and design parameters. Designing/ modelling of dies and workpiece is carried out in SolidEdge V19. The simulation and analysis of this process is accomplished using AFDEX software. Initial temperature range is kept in between 250ºC-400ºC. With variable temperature, 7 iterations were performed and it was found that effective stress is minimum for temperature of 400ºC. 15 iterations were performed in AFDEX simulation software with variable die corner radius and co-efficient of friction to get optimized parameters. Punch velocity is kept at 300mm/s and binder holding force is kept at 730N. The results were tabulated for minimum damage vale, effective stress and effective strain.
