A quantitative analysis of roundness error in cylindrical chuck grinding
International Journal of Machine Tool Design and Research, 1981Abstract Variables that affect the form inaccuracy of roundness in cylindrical chuck grinding have been recognized only in a qualitative manner. This paper presents a new experimental technique which allows the simultaneous and on-line measurement of roundness.

Probabilistic Rounding Error Analysis of Modified Gram–Schmidt
SIAM Journal on Matrix Analysis and ApplicationsAbstract. Building on probabilistic approaches, we study the finite precision behavior of modified Gram–Schmidt (MGS). Based on concentration inequalities and the Sheffield structure, we provide a rigorous probabilistic analysis of MGS in terms of residual, a form of backward error, and loss of orthogonality.

Evaluation Method and Simulation Analysis of Gap Roundness Error
Applied Mechanics and Materials, 2009Theoretical analysis of existing evaluation method of gap roundness error and existing evaluation model of full roundness error is provided. Mathematical model of gap roundness error’s evaluation with least square method is founded based on the evaluation model of full roundness error, which gives a solution of gap roundness error.

Rounding Error Analysis for the Evaluation of a Polynomial and Some of Its Derivatives
SIAM Journal on Numerical Analysis, 1974We consider one-parameter family of Shaw–Traub algorithms (see [3]) for computing a polynomial and its normalized derivatives in floating point arithmetics fl, ${\text{fl}}_{\text{2}} $ and $\overline {{\text{fl}}} $. The numerical stability of this class is proved.

Analysis of influence of Verification strategy on Roundness error Evaluation
2010Coordinate Measuring Machines (CMMs) are widely used in industry to inspect any kind of workpiece form and assess conformity to tolerance specifications. However, for each tolerance, there exist specific instruments, that provide more accurate results, but are not always available in industrial practice.
