Experiment and Simulation of Manufacturing Microparts by Laser Indirect Shocking
One new method based on laser indirect shocking is proposed to manufacture microparts with high efficiency and high precision. Based on the indirect loading mechanism of laser shocking polymers, with different shapes of micromolds and NdYAG-GAIA R laser, it is realized to manufacture microparts on a 35 μm thick Ti sheet under only single laser impact. The experimentally obtained microparts are investigated by the digital measurement system (KEYENCE VHX-1000C), and it is found that within the suitable range of laser power, the microparts have good surface profile, and their forming depth are basically consistent with the pit depth of micromolds. Besides, the forming process of microparts and the thinning rate of the formed parts are investigated by the finite element numerical simulation. The experimental and simulation results show that the good quality microparts can be formed under the single laser impact.
