With the Confovis optical measurement technology, surface topographies and micro geometries up to the nanometre range can be captured. On the basis of the Z coordinates captured confocally or by means of focus variation, the ConfoVIZ© measurement software calculates a point cloud that describes the captured 3D surface. This 3D point cloud can be assessed using the MountainsMap® analysing software. In addition, actual contours can be compared to CAD target data using the PolyWorks® software and evaluated based on characteristics. For the purpose of time-saving measurements, the ConfoVIZ© measurement software measures relevant data ranges, such as for the roughness measurement with a high data density in accordance with standards, according to the patented Structured Illumination method which is one of the confocal measuring processes. It measures micro geometries according to the focus variation working principle with a correspondingly reduced data density which is sufficient for shape or contour analysis.
The application in the industry requires traceable and comparable measurement values which are captured in accordance with the appropriate standards. The surfaces measured with measuring software ConfoVIZ® are traceably and thus comparably analysed in MountainsMap® in accordance with DIN EN ISO 4287/4288 and DIN EN ISO 25178. All results can be verified exactly not only for the mean roughness Ra, but also for the reduced peak height Rpk and the reduced groove depth Rvk by roughness standards of independent providers in accordance with DIN EN ISO 13565.
Shape and contour measurements
The Confovis measurement systems not only measure micro geometries in the research and development sector to secure product developments or optimisation. They also support quality assurance in manufacturing. Alongside the capturing of parameters, such as heights, widths, clearances, angles and radii, motive and particle analyses, as well as volume calculations can be carried out.
Functional volume and texture direction
In order to comprehensively assess the plane, alongside with the arithmetical average roughness value Ra, etc. and Sa, etc. also functional parameters from the derivation of the Abbott curve will be captured. Sk values as well as functional volume parameters, but also the texture direction can be acquired within seconds at the push of a button.
Tribology and material ratio
Tribological functional planes resulting from honing or finishing require an assessment that reaches far beyond capturing the arithmetical average roughness value Ra. In order to make assertions on the surface quality after appropriate processing, at least additional parameters, such as reduced peak height Rpk and reduced groove depth Rvk must be captured.With the Confovis contactless measurement technology micro structures are captured holistically and assessed not only on a profile-base, but also on plane-base.
Cutting edge analysis
For achieving the optimal cutting edge several factors, such as material, processing technology, etc. are to be considered. In order to assess the cutting edge quality / edge rounding, particularly the cutting edge radius and the K-factor will be considered during the cutting edge analysis. With the Confovis measurement systems these parameters can be captured quickly and reliably. Thanks to the three dimensional measurement, defects and faults can be exactly illustrated down to the nanometre range.
