Abstract

An on-machine laser polishing system is developed to suppress the periodic turning marks on diamond turned metal surface. By integrating laser polishing on an ultra-precision machine tool, this method enables high-efficiency non-contact polishing without taking off workpiece from the lathe. Molecular dynamics simulation and experimental validation prove the process’ capability to reduce surface roughness through atomic level material flow from peak to valley. Surface quality has been improved through effective suppression of the diffraction and rainbow effects after laser polishing, demonstrating a high-efficiency, low-cost and clean solution for high-end optical component manufacturing.
