Application of Correlation Function for Analysis of Surface Structure Shaping by Hybrid Manufacturing Technology

The article is focused on determining the optimal parameters of surface treatment using hybrid machining-milling and burnishing. Optimal SGP 3D conditions may be achieved on a previously milled surface using specific parameters in the technological burnishing process. The authors present a method of evaluating the differences in surface topography of milled and then burnished surfaces using cross correlation. This approach can be used for optimizing hybrid technology as well as to track surface texture changes (e.g. analysis of regeneration of machining marks during cutting).
