Abstract
A mathematical model is given for the metal forming in an axisymmetric nonc onical converging die. By using the Maple V system a semianalytical algorit hm is proposed for the calculation of the optimal shape of the die which mi nimizes the consumed energy of the deformation and the power of the frictio n forces at the wall. Two examples are presented to demonstrate the efficie ncy of the proposed method. (C) 1999 Elsevier Science Ltd and Civil-Comp Lt d. All rights reserved.
