Process Planning for a Milling Machine From a Feature-Based Design

April 1, 1988
Author(s)
Thomas R. Kramer
In the Vertical Workstation (VWS) of the NBS Automated Manufacturing Research Facility, metal parts are machined automatically from a feature-based design. A simple two-and-a- half dimensional part may be designed and machined within an hour, allowing half

Cone Calorimeter Evaluation of the Flammability of Composite Materials.

March 1, 1988
Author(s)
James E. Brown, E Braun, W H. Twilley
A study was undertaken to evaluate the fire performance of composite materials using the cone calorimeter as the bench-scale method of test simulating the thermal irradiance from fires of various magnitudes. Five parameters were derived from the

Implementation of the Coordinate Measuring Machine Controller

March 1, 1988
Author(s)
Howard T. Moncarz, Ted Hopp, P Leazark
This document describes the implementation specifics of the Coordinates Measuring Machine Controller (CMMC) program as of March 26, 1987. This program runs under the control of the ECS program that is described in the document Implementation of the

Linear and Non-Linear Atom Optics with Bose Einstein Condensates

March 1, 1988
Author(s)
S L. Rolston
A sample of Bose-Einstein condensed atoms is an ideal source for atoms optics experiments due to the low velocity spread, the large number of atoms, and the coherent nature of the condensate. We have performed a series of experiments using condensates of

Spin Sensitivity of a Channel Electron Multiplier

March 1, 1988
Author(s)
R E. Scholten, Jabez McClelland, Michael H. Kelley, Robert Celotta
We report direct measurements of the sensitivity of a channel electron multiplier to electrons with different spin orientations. Four regions of the multiplier cone were examined using polarized electrons at 100-eV incident energy. Pulse counting and

Available Robotics Technology for Applications in Heavy Industry

February 12, 1988
Author(s)
James S. Albus, Nicholas Dagalakis, B Wang, J Unger, Jonathan W. Lee, C W. Yancey
The need for automation and the use of robots in the heavy construction industry and large scale assembly is examined. Some problems relating to the operation of cranes, like low load stiffness to rotation in all directions and translation in the
