Description

Surface roughness data from CNC turning of AISI 12L14 steel. The package contains 2,448 acquisitions for six surface descriptors and the measurement hierarchy for 68 specimens, 204 axial regions, and 816 circumferential locations. It includes experimental source records, a column dictionary, distribution summaries, statistics for three acquisitions per location, the 17-run central composite design, factor levels, and Ra scenario means. Scripts reproduce the tabular preparation, descriptive summaries, and figures. Supplementary Table S1 documents source-selection categories and criteria.
