Abstract: The surface quality of mechanical components plays a critical role in modern high-end manufacturing, directly affecting equipment performance, service life, and reliability. As the precision requirements for parts in industries such as aerospace, precision instruments, and medical devices continue to increase, traditional surface inspection and machining technologies struggle to meet the demands of ultra-precision manufacturing. In response, this study focuses on key technical issues related to the surface quality inspection and ultra-precision machining of mechanical components, aiming to develop an efficient, accurate, and quantifiable detection method integrated with advanced ultra-precision machining processes to enhance surface quality. The research employs multi-modal inspection techniques, including optical interferometry, atomic force microscopy analysis, and digital image processing, to construct an artificial intelligence-based surface defect recognition model, achieving precise characterization of surface features at the micron and even nanometer levels. Simultaneously, by introducing non-traditional machining technologies such as magnetorheological polishing and ion beam machining, the study optimizes the process parameters for complex curved surface components, significantly reducing surface roughness and improving material removal efficiency. Experimental results demonstrate that the proposed integrated detection and machining solution can effectively identify and correct microscopic surface defects, reducing post-machining surface roughness to sub-nanometer levels while markedly enhancing consistency. A major innovation of this study lies in the deep integration of intelligent detection technology with ultra-precision machining processes, overcoming the limitations of traditional methods in terms of accuracy and efficiency, and providing a new technical pathway for high-end manufacturing with significant theoretical value and practical application potential.
