Recent calculations indicate that Atlas liners must have waviness amplitudes less than 10 nm over spatial wavelengths near 1 cm 11. A liner for Rancher0 has been produced, on equipment at LANL, with waviness amplitudes as close to 10 nm as was possible. A lathe, with air bearing slideways and spindle, was used in concert with a single crystal diamond tool to produce this part. Since the dimensional characterization of this liner can be as challenging as the production, on-machine gauging techniques were used for much of the dimensional inspection. This paper discusses the fabrication and metrology of this ultra smooth liner.
