31. Error Analysis of a Hexapod Machine Tool
Published: 4/3/1997
Author: Johannes A Soons
Abstract: This paper describes the measurement and analysis of the quasi-static errors of a prototype hexapod milling machine at the National Institute of Standards and Technology (NIST). Emphasis is placed on a) the identification and definition of the parame ...

32. Magnetic field dependence of the critical current anisotropy in normal metal-YBa,Cu307-delta thin-film bilayers
Published: 3/18/1991
Authors: Ronald H. Ono, Loren F Goodrich, James A Beall, Johannes A Soons, Carl D Reintsema
Abstract: We have measured the transport critical current density (Jc) in epitaxial quality films of YBa2Cuj07-delta some of which were covered by thin (10 nm) Ag films. The films, both with and without Ag, had Jc values greater than 10^6 A/cm2 in liquid nit ...

33. Performance Evaluation of a Parallel and a Hybrid Machine Tool
Series: Journal of Research (NIST JRES)
Report Number: 6567
Published: Date unknown
Authors: Johannes A Soons, S M Athavale, R Furness
Abstract: vances in both the technology and cost of controllers have enabled the commercial introduction of machine tools with a parallel configuration of the positioning axes. In theory, this radical change in design enables improvements in key machine chara ...
