The Mathematical Model

In order to predicate machined shape of electrochemical machining (ECM), a machined shape prediction method by using numerical simulation is presented in this paper. For the simulation, the mathematical model based on electric field and flow field theories firstly is built. Then the time discretization method and the finite element method (FEM) are employed to solve the mathematical model. The simulation software is developed to perform the simulation of the ECM process and predict the machined shape. Finally the method is applied in the ECM processes of the blade and the cavity. The application results show that the machined surface with high accuracy can be achieved and less test times is needed by the simulation.

Good Agreement

This work presents numerical simulations and an experimental validation of sheet laser forming processes using general scanning paths with different laser beam operating parameters (i.e., power, diameter, and scanning speed) in two specific graphite coated stainless steel blanks (i.e., with thicknesses of 0.3 mm and 0.6 mm for the AISI 302 and 304 alloys, respectively). To this end, three specific laser forming tests involving single S-shaped, multiple circular, and single piecewise linear scanning paths are carried out. On the other hand, the numerical simulation of these tests is performed via a coupled thermomechanical finite element formulation, accounting for large viscoplastic strains, temperature-dependent material properties, and convection-radiation phenomena. The final bending angles provided by this model are found to be in good agreement with the experimental measurements for all of the cases studied. Therefore, this modeling framework can be established as a reliable approach to predict the material thermomechanical response during sheet laser forming using general scanning paths.
