Finite-Element Simulation of Microforming Based on Laser-Assisted Heating
To solve the forming difficulty in the microforming microparts made of hard-to-deform material, a novel approach about micro plastic forming based on laser-assisted double-sided heating method has been presented. Numerical simulations are completed and analyzed using a finite element method (FEM) softwave, ABAQUS to study the temperature field distributions and the stress distributions of the billet and the effect of laser-assisted heating on the characteristics of microforming. Accordingly, the coupled thermo-mechanical finite element model of cylinder billet is developed.The results show that an appropriate temperature field for microforming can be established using the laser-heating method, resulting in the decrease of microforming force and the improvement of formability of microforming material. The novel method will extend the applications of microforming.
