The holistic approximation with integrated partitioning and iterative root point calculation can cope even with modified flanks and is validated for gear parameter estimation with systematic deviations <0.2 µm. Apart from low signal-to-noise-ratio cases, where the approximation suffers from the multidimensionality of the optimization, the accuracy of standard evaluation procedures is achieved. Furthermore, holistic approximation is able to perform the required mathematical separation of the integral geometric elements of a tooth flank automatically when determining unknown gear parameters.enCC BY-NC-ND 4.0 (Attribution-NonCommercial-NoDerivatives)https://creativecommons.org/licenses/by-nc-nd/4.0/GearMetrologyReverse engineering600 Technik, Medizin, angewandte Wissenschaften::600 Technik::600 Technik, TechnologieText::Zeitschrift::Wissenschaftlicher Artikel10.26092/elib/3328urn:nbn:de:gbv:46-elib82944
