Using conventional deep drawing method, it is difficult to make square cups taller than the length of straight side of punch in only one stage drawing. This is because, in case of using a conventional, the drawing resistance of blank material is too high to draw material into die hole by punch. From simple consideration, by using the developed blank, the flange portion of which is divided into four elements, the drawing resistance of blank material can be reduced considerably, and so this problem can be overcome. In this investigation, a deep drawing process of square cup was attempted using a developed blank instead of an octagonal or ellipse blank. By introducing assumption of the constant arc length, the shape of developed blank was designed. It was clarified that, when developed blanks with appropriate shape was employed, very tall square cups could be obtained in one stage drawing.
