Forecast of the fatigue crack initiation site of commercially pure Titanium miniature specimens with local surface topography data Open
Surfaces of technical components rarely appear in perfectly smooth condition. During fatigue loading, stress concentrations at surface asperities cause localized plastic deformation that can lead to crack initiation. Therefore, we have est…

Approach for the observation of surface conditions in-process by soft sensors during cryogenic hard turning Open
Even though required for a robust production, direct measurement of the surface condition in-process is a challenge due to technical limitations. A concept for in-process monitoring of surface conditions like hardness or microtopography us…

Extensive microstructural quality control inside a machine tool using multiwavelength digital holography Open
With state-of-the-art 3D measurement systems, short-wave structures such as tool marks cannot be resolved directly inside a machine tool chamber. Up to now, measurements had to be performed outside the machine tool. We present an interfero…
