TL;DR: In this article, it was shown that fdr depends on relative velocity, v, and concentration, ρ, of the polisher suspension, and therefore the Preston equation has to be modified i.e. h = h(ffr(v), ρ).

TL;DR: A mathematical treatment is developed to establish the difference in the sagitta between toroidal and off-axis conic surfaces, and the best fit is found by optimizing the curvatures of the toroid.

TL;DR: An ideal Twyman-Green interferogram with equally spaced straight fringes parallel to the x axis and fringe coordinates that are affected by Gaussian errors is considered and it is shown that deviation increases with the noise level and decreases with the number of fringes.

TL;DR: Applying the least-squares methods to data points of a pattern border, the center and radius of a circular pattern is estimated.

TL;DR: In this article, a generalized equation was used to describe and speed up numerical calculations of the inner points of both known and other asymmetrical tools, and wear profiles were obtained for different shape tools and oscillation amplitudes.
