Algorithm for the geometric configuration of the reconfigurable multipoint forming dies

Résumé

Multipoint forming of thin steel plates with special equipments is based on the discrete die-punch reconfigurable tooling concept. The geometric modeling of the die-punch tool requests calculations of the characteristic profiles coordinates of the working surfaces materialized by a number of punches on the height positioned. The paper is concerned with the development of a method for die – punch geometry configuration using Matlab program. On this basis, the theoretical analysis is particularly applied to the simulation of the doubly curved thin steel plate deformation using finite element method. The conclusions obtained from the numerical simulation certify the validity of the developed method.
