The NCMS Volumetric Accuracy for Large Machine Tools (VALMT) project is the subject of an article in the latest issue of Quality Digest.
…The entire measurement process can be accomplished in a matter of hours rather than days, resulting in more accurate measurements and eliminating costly machine downtime. Calibration is performed in a single set-up with automated measurement of hundreds of points and is completed in just a few hours compared to alternate methods that can take much longer. By accomplishing the measurement task in such a short timeframe, the measurement data is far more reliable.
The VALMT project has pioneered an innovative process in establishing a new methodology in volumetric error compensation for large machine tools which can save the Department of Defense (DOD) and the commercial aircraft industry millions of dollars anually.
