Abstract
The rapid development in the field of mechanical manufacturing puts forward higher requirements for the surface performance of parts, and the surface integrity technology, as a key means to improve the service performance and life of parts, has become one of the core contents of modern manufacturing technology research. Aiming at the formation mechanism of surface integrity during machining, we deeply explored the intrinsic connections between surface microstructure, residual stress distribution, and material properties. By combining numerical simulation and experimental validation, we construct a multi-scale surface integrity evaluation system, and propose a surface integrity control strategy based on the optimization of process parameters. The results show that reasonable regulation of cutting parameters can significantly improve the surface roughness and residual stress state, thus effectively delaying the initiation and extension of fatigue cracks. In addition, this research innovatively introduces the artificial intelligence algorithm to predict and evaluate the surface integrity, realizes the real-time monitoring and adjustment in the processing process, and provides theoretical support and technical support for intelligent manufacturing.
