Multisensor measuring for complex parts
- January 3, 2012
Carl Zeiss's O-Inspect multisensor measuring machine offers easy, accurate and efficient measurement of complext parts, claims the company.
The machine is now offered with a chromatic white light sensor.
The white light sensor enables the measurement of parts that can't be captured with a contact sensor or camera. Reflections or lack of contrast, which can impede the correct focusing of a camera, is no longer a problem. The chromatic white light sensor allows for accurate measurement of such parts.
How the new method works
The workpiece is illuminated with a bundled white light. Special optics with chromatic aberrations in the proble split the light into its spectral colours. A spectrophotometer analyzes the reflected light and determines which colour has the highest intensity. The measuring machine can determine the distance from the sensor to the surface using the spectral colour, and derives the exact topography of the part from this information.
Results are displayed using CAD-based Calypso measuring software. It enables size, form an dposition measurements with user guideance and makes deviations visible and quantifiable. The machine is also equipped with an additional light source on the contact scanning sensor that can be turned on to illuminate the measuring field when the machine is reprogrammed.
