Alicona Launches µCMM – Optical 3D Focus-Variation Measuring Machine

Alicona has launched µCMM, its latest optical 3D Focus-Variation measuring machine, at the Control exhibition in Stuttgart, Germany and comments “This is a new benchmark in production measurement techniques”.

µCMM is the most accurate, purely optical, micro-coordinate measuring system in its class with a stated accuracy of 0.8 + L/600µm to ISO10360-8. Users combine advantages from tactile coordinate measuring technology and optical surface measurement to measure dimensions, position, shape and roughness of components with just one sensor. The new µCMM offers high geometric accuracy of several optical 3D measurements in relation to each other, which enables the measurement of the smallest surface details including accurate measurement of position. 3D measurements take place only at the relevant measuring points thus achieving very fast inspection times. µCMM allows users to measure both surface roughness and GD&T features with tolerances in the single-digit µm range with just one sensor. The spectrum of measurable surfaces includes all common industrial materials and composites such as plastic, PCD, CFRP, ceramics, chrome and silicon including matt, polished and reflective components.

Simple operation is implemented by single-button solutions, automated measuring sequences and ergonomic operating panels such as a specially developed controller. Air-bearing axes with linear drives enable wear-free operation providing high-precision and fast measurement makes µCMM ideal for permanent use directly in production. A fully integrated automatic optics change rack extend the measuring system versatility.

µCMM is designed for easy, flexible, and expandable use by multiple operators implemented through a series of options that extend the application range of the optical CMM and maximize fields of use in production measurement technology. The motorized “Real3D Rotation Unit”, for example, turns the 3-axis system into a 5-axis system and enables users to measure components from several, arbitrary perspectives allowing contactless measurement of surface features such as flank angle, chamfer angle, thread pitch or undercuts.

Measurement automation is implemented using the “AutomationManager” automation interface allowing the µCMM to perform automatic measurement and evaluation of surface roughness and GD&T features. The system administrator defines the associated measuring programs, which are then started by a production operator at the push of a button. Measuring programs can be selected via drop-down menu or using a barcode scanner.  µCMM can be integrated directly into production allowing Smart Manufacturing by connecting and communicate for adaptive and self controlling production.
