With the continuous development of advanced manufacturing technologies, accurate characterization, measurement, and understanding of surface formation processes have become increasingly important in both scientific research and industrial applications. This Special Issue focuses on the assessment of surface topography generated by a wide range of manufacturing processes, including both conventional and non-conventional machining technologies. In addition to surface characterization and measurement, particular attention is given to the mechanisms of surface formation in machining processes. Conventional manufacturing processes such as turning, milling, drilling, grinding, and abrasive finishing remain fundamental in precision engineering. In parallel, non-conventional and hybrid manufacturing technologies, including waterjet machining (WJM/AWJ/PWJ), electrical discharge machining (EDM/WEDM), electrochemical machining (ECM), laser-based processes, and hybrid or assisted machining systems, are increasingly applied for the processing of advanced engineering materials and complex geometries. Recent advances in surface metrology and three-dimensional surface analysis have enabled more detailed investigation of surface formation mechanisms and surface integrity evolution under complex machining conditions. Eco-efficient and sustainable manufacturing approaches are also gaining importance in modern production systems, particularly in the context of reducing environmental impact while maintaining high surface quality. The aim of this Special Issue is to provide a comprehensive platform for high-quality contributions addressing experimental and theoretical studies on surface topography in machining processes.
