The Flagstaff Measuring Machine [PDF]
Symposium - International Astronomical Union, 1990 The U.S. Naval Observatory is building a measuring machine which will hold four PSS plates simultaneously and will automatically measure them, in a highly controlled environment, in about 12 hours. The images will be recorded by two camera subsystems with a scale of 0.9 arcseconds/pixel on a 0.33 × 0.26 degree CCD frame.

Improvement of machining accuracy for 3D surface machining with CNC lathe
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 The present paper describes a new non-axisymmetric curved surface turning (NACS-Turning) method. Fast tool servo (FTS) technology has been widely researched and developed. However, the movable range of the FTS is limited to a few millimeters owing to its

Evaluation of measurement technique for a precision aspheric artefact using a nano-measuring machine [PDF]
, 2013 A precision aspheric artefact is measured in 3D by a commercially available nano-measuring machine (NMM) integrated with a contact inductive sensor as the probe. The mathematics of 3D compensation of the error caused by the probe radius is derived.
