Alicona µCMM
Optical micro-coordinate measuring of dimension, position, shape and roughness in one system
Designed specifically with the production environment in mind the new µCMM is a robust machine offering high accuracy over the entire measurement volume. μCMM is the most accurate purely optical micro-coordinate measuring system in its class.
Users combine advantages from tactile coordinate measuring technology and optical surface measuring technology and measure the dimension, position, shape and roughness of components with only one sensor.

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.
