Surface Roughness Improvement Using Laser-Polishing Techniques
A laser polishing method applied on metallic surfaces is presented in this work. One of the most important applications of this technique is the small-medium injection mould polishing manufactured by rapid manufacturing processes (RM) such as selective laser sintering. The polishing method has been applied to different surfaces including a laser-sintered part. Topography and roughness parameters measurements show that laser polishing can achieve surface improvements up to three times in mean roughness parameter with no macro-geometric deviations.
