21. The Calculation of CMM Measurement Uncertainty via The Method of Simulation by Constraints
Published: 1/1/1997
Authors: Steven David Phillips, Bruce R. Borchardt, Daniel S Sawyer, William Tyler Estler, David E Ward, K Eberhardt, M. Levenson, Marjorie A McClain, B Melvin, Ted Hopp, Y Shen
Abstract: The calculation of task specific measurement uncertainty when using coordinate measuring machines is an important and challenging task. Current methods to address this issue use simulation techniques (e.g., the virtual CMM) where the propagation of k ...

22. Error Compensation for CMM Touch Trigger Probes
Published: 10/1/1996
Authors: William Tyler Estler, Steven David Phillips, Bruce R. Borchardt, Ted Hopp, G Witzgall, M Levenson, K Eberhardt, Marjorie A McClain, Y Shen, X Zhang
Abstract: We present the analysis of a simple mechanical model of a common type of kinematic seat touch trigger probe widely used on modern coordinate measuring machines (CMMs). The model provides a quantitative description of the pretravel variation or probe- ...

23. NIST SRM 9983 High Rigidity Ball-Bar Stand User Manual
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5659
Published: 6/1/1995
Authors: Daniel S Sawyer, Steven David Phillips, Gregory W Caskey, Bruce R. Borchardt, David E Ward, P Snoots
Abstract: This document is the user manual for the NIST SRM 9983 High Rigidity Ball Bar Stand. The manual contains a list of the components that are included as part of the unit. Complete instructions for setting up and assembling the stand to support a ball b ...

24. The Estimation of Measurement Uncertainty of Small Circular Features Measured by CMMs
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5698
Published: 2/1/1995
Authors: Steven David Phillips, Bruce R. Borchardt, William Tyler Estler
Abstract: This paper examines the measurement uncertainty of small circular features as a function of the sampling strategy, i.e., the number and distribution of measurement points. Specifically, we examine measuring a circular feature using a three-point samp ...

25. User Manual for the Interim Testing Artifact for CMMs
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5602
Published: 2/1/1995
Authors: Amy Singer, J Land, Steven David Phillips, Daniel S Sawyer, Bruce R. Borchardt, Gregory W Caskey, et al
Abstract: The Interim Testing Artifact (ITA) is designed to quickly test CMMs for performance problems so that they can be repaired before significant numbers of good parts are erroneously rejected (or bad parts accepted) by the CMM. Frequent testing using the ...

26. Error Compensation for CMM Touch Trigger Probes
Published: 1/1/1995
Authors: William Tyler Estler, Steven David Phillips, Bruce R. Borchardt, Ted Hopp, Christoph Johann Witzgall, M Levenson, et al
Abstract: We present the analysis of a simple mechanical model of a common type of kinematic seat touch trigger probe widely used on modem coordinate measuring machines (CMMs). The model provides a quantitative description of the pre-travel variation or probe ...

27. Pitch Diameter Measurement of Threaded Gages Using a CMM
Published: 1/1/1995
Authors: Ralph C. Veale, Edgar G Erber, Bruce R. Borchardt
Abstract: The reference datum for a screw thread is the pitch diameter cylinder. Although a defined method within the United states for pitch diameter measurement exists, it does not follow worldwide procedures, and the complexity and uncertainties associated ...

28. A Users' Guide to NIST SRM 2084: CMM Probe Performance Standards
Published: 6/1/1994
Authors: Gregory W Caskey, Steven David Phillips, Bruce R. Borchardt, David E Ward, Daniel S Sawyer
Abstract: Standard Reference Materials (SRMs) as defined by the National Institute of Standards and Technology (NIST) are well-characterized materials, produced in quantity and certified for one or more physical or chemical properties. They are used to assure ...

30. A Novel CMM Interim Testing Artifact
Published: 1/1/1994
Authors: Steven David Phillips, Bruce R. Borchardt, Gregory W Caskey, David E Ward, Bryon S. Faust, Daniel S Sawyer
Abstract: NIST is currently developing equipment and techniques to rapidly access the performance of Coordinate Measuring machines (CMMs). This will allow the frequent testing of CMMs to insure that they measure parts accurately. A novel interim testing artifa ...
