Robust optimization of multi-probe roundness measurement probe angles

Positional errors of a multi-probe roundness measurement frame will result in the probe angles deviating from nominal angles. The actual can be accurately determined after placing using cross correlation or other methods. However, since methods suffer harmonic suppression, determining is not enough for accurate reconstruction profile, if are situated an area with poor characteristics. To find suitable areas to allow deviations angles, this paper presents robust optimization avoid suppression regardless Suggestions optimal presented three-point and four-point redundant diameter method.
