Application of FEM simulation to AI V-bending process control

Abstract

In this study, an artificial intelligent (AI) V-bending process control system with FEM simulation database was developed in order to achieve the production with high accuracy and flexibility. An adaptive filter was proposed to modify the simulated punch force-stroke curve (F-S curve) and to obtain the pseudo experimental one. The filtered simulation results are stored in the database and used to the V-bending process control with an intelligent process control system developed by the authors. The process controlled results show that the FEM simulation database with the compensation filter is very effective for the precision process control system. A high accurate V-bending process was achieved without the trial and error of V-bending tests.
