Laser remanufacturing has been used as an approach to refurbish or to improve the surface quality of high-priced parts. However, most of the existing systems lack measuring and modelling functions, which results in the uncertainty of the quality of end products. This paper presents a three-dimensional Laser Remanufacturing System (LRS) based on the integration of reverse engineering and laser c...
