Titanium alloys, namely Ti-6Al-7Nb, are used in the biomedical industry. The study of surface topography is crucial for the development of medical components. The objective of this work is to propose the correlative microscopy technique developed for the analysis of surfaces machined by the turning process of Ti-6Al-7Nb alloy. This technique was based on the association of the 3D reconstruction by extended depth- of-field method from Optical Microscopy (OM) with the Scanning Electron Microscopy (SEM) and microanalysis modes. The correlative microscopy allows a correspondence between the cutting conditions and the material properties, through the analysis of the machined surface.
