Author(s)

Steven D. Phillips, Bruce R. Borchardt, Daniel S. Sawyer, William T. Estler, David E. Ward, K Eberhardt, M. Levenson, Marjorie A. McClain, B Melvin, Ted Hopp, Y Shen

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 known

The Calculus of Imprecision for the Analysis and Evaluation of Engineering Models

January 1, 1997

Author(s)

Ronald Giachetti

Engineering design is characterized by a high level of imprecision, vague parameters, and ill-defined relationships. In design, imprecision reduction must occur to arrive at a final product specification. Few design systems exist for adequately

The dynamics of chip formation in machining

January 1, 1997

Author(s)

Matthew A. Davies, Christopher J. Evans, Timothy J. Burns

In this paper, we provide experimental, numerical and analytical evidence suggesting that the onset of segmented chip formation is the result of a Hopf bifurcation in the material flow. We modify the conventional one-dimensional model for orthogonal

The Guidelines for Expressing Measurement Uncertainties and the 4:1 Test Uncertainty Ratio

January 1, 1997

Author(s)

Jun-Feng Song

In 1988, MIL-STD-45662A adopted the 4:1 Test Uncertainty Ratio (TUR); this was later incorporated into the ANSI/NCSL Z540-1 standard in 1994. However, in 1992, the National Institute of Standards and Technology (NIST) began to adopt a new method for
