Thesis summary
Surface quality is a key factor in the performance and reliability of machined components. As production systems evolve toward “zero-defect” strategies and in-process control, it becomes essential to link machining behavior, surface formation, and measurement reliability within a coherent framework. This doctoral thesis proposes an integrated methodology combining cutting mechanics, signal analysis, and artificial intelligence to predict and control surface quality during machining.
Interpretable AI models are being developed to establish the link between signals, machining parameters, and surface roughness, thereby forming the basis of a proactive quality control framework. At the same time, multiscale analysis techniques are being introduced to characterize texture evolution beyond conventional roughness indicators, while AI-based approaches are being explored to improve the robustness of non-contact optical measurements.
The objective of this thesis is to contribute to the development of intelligent and reliable manufacturing systems by enabling earlier detection of surface defects and supporting data-driven decision-making in machining processes.
