Optimum Sheet Forming Process Design by Using FE Analysis and Mathematical Programing
Until now, in the forming process design the data base decision system based on expert’s experience and experimental observation has been employed commonly. This paper newly proposed the optimum process design system based on two numerical simulation schemes. One is the forming simulation by using the finite element method -ROBUST-. Another is the mathematical programing, such like the grid search and simplex methods. In this system, the objective function is formulated by the design parameters, such like sizes of tools, stages of process and material properties. The optimum search is performed under the constraint condition by employing the nonlinear programing and finite element methods.
