Mechanical Measurements & Calibration
PDF format (173 kb)
The Measurement and Calibration teams perform precision mechanical calculations using state-of-the-art equipment in a controlled temperature laboratory. Capabilities include in-process and final dimensional measurements, pre-testing and post-testing of data, measurement consultation, solid model inspection, and calibration of length, mass, and force. Complex characterization of known and unknown geometries is performed to accuracies within millionths of an inch and 0.2 arc seconds.
