Strategic Study of CAE 2020, Volume 22, Issue 3,   Pages 63-70 doi: 10.15302/J-SSCAE-2020.03.011

Abstract:

Laser remanufacturing technology, as the frontier of manufacturing technology innovation, has profoundly changed the design and operation of high-end equipment. It is a critical supporting technology for green remanufacturing and an important force to promote sustainable development of manufacturing industry. In this study, the macro-demands of laser remanufacturing technology were analyzed. The development and application status of laser remanufacturing technology were introduced in detail. The challenges in development of laser remanufacturing technology and industry were summarized. Then, the staged development goals for 2025, 2035 and 2050 were proposed. Regarding the current challenges of laser remanufacturing technology in China on special materials, core components, remanufacturing concepts and standard systems, development suggestions were proposed: strengthening the active guidance at the strategic level; constructing the genome system for laser additive remanufacturing materials; improving the standardization system and the high-level applied talent training system; increasing application promotion and guiding industry integration; establishing cooperation platforms to accelerate the innovation development of key common technology, and providing support for laser remanufacturing technology and its industrial development.
