A groove at the outer surface on the flange is usually made by cutting or casting method. In usual method of plastic working, it takes much times and many process. Plastic working has many advantages, for example, high utilization ratio, redaction of the processing cost by mass production and so on . Then, a purpose of this investigation is to establish for forming of the flange with grooves in experiment and FEM analysis. Forming processes are divided into 3 processes, which are deep drawing, compressing of the cup edge and reverse redrawing. A formable area of the flange in reverse redrawing is shown by FEM analysis and experiments. When thickness and diameter of the blank are varies the formable area is examined. This investigation is reported about the forming of the flange without grooves.
