Alicona µCMM
Optical coordinate measuring machine (CMM) for dimension, position, shape and roughness
The Alicona µCMM is an optical micro-coordinate measuring (CMM) device for analysing dimension, position, shape and roughness in one single system. The µCMM is ideal for measuring small surface details on large components, working at the highest degree of precision needed for medical device, aerospace, automotive and other precision manufacturing markets. The upgrade from 3 to 5 axes allows the non-contact measurement of components that were once difficult or impossible to achieve.
Designed specifically for the production environment, the Alicona µCMM is the most accurate, purely optical micro-coordinate measuring system in its class. The µCMM combines the advantages of tactile coordinate measuring technology with optical surface measuring technology with Focus-Variation for the ultimate non-contact metrology experience.
The Alicona µCMM can be used on all surfaces including matte and highly polished components for greater flexibility within your testing and inspection process. It’s extremely easy to use, boasting a single-button solution, automation and ergonomic control elements for comfort. Designed to be a permanent feature of your production process, the Alicona µCMM is wear-free thanks to air-bearing axes with linear drive.

Case Study
Gear shaft malfunction inspection with the optical CMM machine
The µCMM optical CMM machine with a µCMM Real3D rotation unit was used to measure a faulty gear shaft. In order to analyze the malfunction of this gear shaft part, the following parameters need to be measured:
- coaxiality of gearing in respect to the shaft
- outer diameter of gearing and shaft areas
- shaft lengths
- profile & areal roughness on the tooth flank
- parameters to qualify the gearing itself
An automated routine was developed. The component is clamped in the Real3D rotation unit and for shape, distance and position measurements the 1500A objective is used. Then for surface finish measurements the system automatically switches to a 800A objective. The routine measures and assesses sample areas of the component, taking in total less than 10 minutes.
