3D Focus-Variation Measuring

Description

µCMM is the most accurate optical micro-coordinate measuring system in its class. Users combine advantages of tactile coordinate technology and optical surface metrology to measure dimensions, position, shape, and roughness of components with just one sensor. The µCMM offers high geometric accuracy of several optical 3D measurements in relation to each other, which enables the measurement of smallest surface details including precise determination of position. The 3D measurement takes place only at the relevant measuring points and thus in a very short time. With only one sensor, users measure both surface roughness and GD&T features with tolerances in the single-digit µm range. The spectrum of measurable surfaces includes all common industrial material and composites such as plastic, PCD, ceramics, etc. including matte and polished, highly reflective components. The simple operation is implemented by single-button solutions, automated measuring sequences and ergonomic operating panels such as a specially developed controller. An automatic objective magazine further supports flexible usage and easy handling. Air-bearing axes with linear drive enable wear-free use and high-precision, fast measurement. This makes µCMM ideal for permanent use in production.

 

A series of options extend the µCMM´s application range and maximizes fields of use in production measurement technology. As of example, the motorized rotation unit “Advanced Real3D Rotation Unit” turns the 3-axis system into a 5-axis system and enables users to measure components from several, arbitrary perspectives. This allows contactless measurement of surface features such as flank angles, chamfer, thread pitch or undercuts.

 

Another feature is measurement automation, achieved by the "AutomationManager" automation interface to be able to fully automatically measure surface roughness parameters and GD&T features. An administrator defines the required measuring programs, which are started by an operator in i.e. the shop floor at the push of a button. The programs to be measured are selected via drop-down menu or barcode scanner. The measurement result is then completely operator-independent.

 

µCMM is also ready to be used in modern manufacturing concepts, based on integrated production concepts as it is with Industry 4.0 or Smart Manufacturing. Here, machines, production systems and measuring instruments connect and communicate with each other to enable adaptive and self-controlling production.
