tical path of One of the most distinctive advantages enabled by InfiniteFocus is the measurement of
ing on the the ‘real’ edge contour. The common approach for measuring edges has been to simply fit
on as it hits a radius into a relatively large section of the edge itself. However, the application work of

elliptic shape requires a significantly higher lateral and vertical resolution. With a vertical

In terms of tactile measurement, tool manufacturers often consider the measurement of
only a single track as insufficient because this leads to a high measurement uncertainty.
With the Alicona system users are now able to measure edge radii below 10um and
components with flanks up to 87°

ical industry, measurement of components directly in the machine tool. The revolutionary production
concept is based on the integration of a Focus-Variation measurement sensor in a
machining center. Miniaturized EDM components with complex geometries are
manufactured using continuous high resolution measurements for inspection.
