The Precision Alignment of a Kolsky Bar Apparatus

January 1, 2002
Author(s)
Timothy J. Burns, Brian S. Dutterer, Michael Kennedy, Matthew A. Davies, Richard L. Rhorer
The modeling of machining processes is often limited by the availability of material data appropriate for the high strain rates and rapid heating associated with the metal cutting process. A new NIST facility - the pulse heated Kolsky bar apparatus - has

Evaluating the Performance of Rapid Prototyping/Rapid Manufacturing Systems

September 28, 1998
Author(s)
Richard L. Rhorer, Kevin K. Jurrens, Bradley N. Damazo
A method of fabricating and measuring simple part shapes to evaluate the performance of Rapid Prototyping (RP) systems is proposed in this report. These test shapes would include cylinders, rectangular bricks, cones, and other basic shapes. We propose a

Collaborating on the Design and Manufacture of an Atomic Artifact Transport System: A Case Study in VRML as a Visualization Tool for Consensus Building

September 1, 1998
Author(s)
Robert Allen, Srinivas Nidamarthi, P V. Rao, Richard L. Rhorer, Ram D. Sriram, E C. Teague
We report on our experience using the Virtual Reality Markup Language (VRML) to collaborate on the design and manufacture of an artifact transport system (ATS). Specifically designed for the purpose of transporting nanometer-scale dimensional artifacts at

Fabrication of Optics by Diamond Turning

January 1, 1995
Author(s)
Richard L. Rhorer, Christopher J. Evans
The use of special machine tools with single-crystal diamond-cutting tools to produce metal optics is called diamond turning. The manufacture of optical surfaces by diamond turning is relatively new compared to the traditional optical-polishing methods. In
