The utilization of the robust design Taguchi realizes the optimization of the laser beam reshaping of the cogged wheels made of plastic material. The experiments realized so far, have followed to relate the laser beam parameters and to establish the nominal optimum values of these ones, so that, to be able to control the shape, the dimensions and the state indicators of the wheels surface, and the processing efficiency to be the highest possible. The plastic material cogged wheels obtained through unconventional technologies (processing with CO2 laser) are used especially for prototypes due to their high productivity and low producing costs compared to the ones obtained through conventional technologies.
