Abstract
A systematic approach predicting the possibility of forming complex shapes in hydromechanical deep drawing has been developed The method is based on knowledge about the limiting curve of drawing-in of the flange caused by fracture, adopting different initial drawing ratios, when drawing circular cylindrical cups. This limiting curve is called the master curve. Using geometrical considerations the curve representing drawing-in of the flange in hydromechanical deep drawing of a complex shape is constructed and compared with the master curve. Successful predictions of the possibility of forming or fracture in drawing stepped and conical cups in stainless steel were obtained.
