Abstract: 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 cladding. A coaxial powder feeding system is developed to meet the requirement of three-dimensional laser cladding. Meanwhile, the geometric and mechanical properties of metal parts of layers fabricated by LRS are explored. In addition, the principal, advantages and applications of the LRS system are described.

Keywords: laser remanufacturing; reverse engineering; 3D laser cladding; repair technology; CADCAM; coaxial powder feeding.
