amongst other things, enabled by the high measurement speed and high vertical ATC

By integrating the measurement unit into the machine tool the coordinate systems of the
machining center and the optical sensor are the same and the need to unclamp and
reclamp the component for quality control is eliminated. Due to the closed loop JH. L
"processing-measuring-modifying-processing”, an up to four fold increase in accuracy is 1 Chai
provided. Additionally, the elimination of clamping errors, automated quality assurance, 2 | nsti
resource savings of 25%, a more efficient deployment of personnel and shorter lead times of Tec
at a better output ratio are the main benefits of closed-loop manufacturing. 3 Aust
6. SUMMARY
ABS
Focus-Variation is used for the characterization of micro-structured surfaces. In the field of
corrosive investigation the technology is applied to the analysis of different forms of The s
corrosion, corrosive data and clarification of individual corrosive mechanics. The high |
knowledge about circumstances causing erosive and corrosive attack of material surfaces angul:
and protective layers of components leads to the establishment of new guidelines to electr
develop more resistant material. In particular, profile and area measurements are used for entrar
further mathematical computations of degradation rates. Also, measurement data and 3D knowr
visualizations of fractured surfaces are used for further research and development mech:
activities. from t
The technology is a well-established technique to characterize surfaces with complex within
geometries. Typical surface features coming along with corrosive specimen are steep relate:
flanks and highly reflective properties. The vertical resolution up to 10nm can also be
achieved at very inhomogeneous and rough geometries.
