Abstract
Micro-nano manufacturing technology plays a crucial role in modern precision manufacturing, where surface quality directly affects the performance and reliability of devices. To meet increasingly stringent application requirements, this study focuses on the control and optimization of surface quality in micro-nano processing, aiming to propose effective solutions for enhancing processing accuracy and surface integrity through systematic analysis and experimental exploration. By integrating theoretical modeling, numerical simulation, and experimental validation, the study thoroughly investigates the influence mechanisms of various processing parameters on surface roughness, residual stress, and micro-topography, while incorporating advanced online monitoring techniques to enable real-time feedback and regulation of the processing procedure. Based on these findings, an optimization algorithm incorporating multiphysics coupling analysis has been developed, capable of generating optimal parameter combinations tailored to specific materials and processing conditions. Experimental results demonstrate that this approach can reduce surface roughness by approximately 30% while effectively minimizing subsurface damage, thereby improving the functional characteristics and service life of devices. Additionally, the surface quality evaluation system proposed in this study exhibits broad applicability and can be extended to various micro-nano processing scenarios. The research not only provides new insights into surface quality control in the field of micro-nano processing but also lays an important foundation for technological upgrades in high-end manufacturing industries.
