The ETALON solution – volumetric machine calibration with submicrometer accuracy

Using the ETALON system, the geometric variations of a machine can be measured quickly and very accurately. The traversing paths of the machine are automatically traced in space by the LaserTRACER and evaluated using a patented process. Extremely high accuracy is achieved as a result of distance measurements in space using a high-resolution interferometer. The procedure is also used to calibrate highly accurate coordinate measuring devices.

The interferometer has a resolution of 1 nm with a maximum measuring length of 15 m. The LaserTRACER-MT with a measuring radius of between 260 and 940 mm can be used as an alternative. The automatically generated compensation data can then be directly transferred to a SINUMERIK CNC. Using the SINUMERIK Run MyCC /VCS option, systematic deviations are compensated throughout the working area. This usually multiplies the spatial accuracy of the machine.
