Carl Zeiss IMT Blade. Pro Functional Range • Computation of geometric characteristics as thickness, length, stacking point, etc. • 3 D best fit by methods of Gauss, Tschebyscheff, and modifications of these types • Selectable degrees of freedom • New kind of best fit procedure implementing the extension/contraction of the nominal profile in order to deal with large length errors (patent applied) Daniel Görsch 22. 11. 2020 Carl Zeiss © 2003 9
Carl Zeiss IMT Blade. Pro Features An assortment of selectable characteristics: • • • Shape deviation of the section profile Maximum blade thickness Maximum blade length Thickness of leading and trailing edge Radius of leading and trailing edge Thickness at arbitrary positions of the section profile Twist angle of the section Stacking point Chord line length Mean line, tangent line, etc. Daniel Görsch 22. 11. 2020 Carl Zeiss © 2003 10
Carl Zeiss IMT Blade. Pro Features Selectable best fit methods: • • Method by Gauss (least error squares) Method by Gauss (weighted by tolerances) Method by Tschebyscheff (minimal maximal error) L 1 -Method (least absolute error values) Selectable best fit degrees of freedom: • Standard degrees of freedom (rotation, translation, offset) • Degrees of freedom for extension/contraction of section profiles Daniel Görsch 22. 11. 2020 Carl Zeiss © 2003 11
Carl Zeiss IMT Blade. Pro Best Fit Transformations Selectable best fit transformations: • Standard (the same as in KUM, Calypso, etc. ) • Standard with offset • Elongation - compensation of global length errors (changes the entire profile) • Shift Elongation - compensation of local length errors at the edges (changes only edges of the profile) The last two transformations change the nominal section profile data! Daniel Görsch 22. 11. 2020 Carl Zeiss © 2003 12
Carl Zeiss IMT Blade. Pro Best Fit Transformations - Elongation Right Profile Left Mean Line Point Right Mean Line Point The section profile is split into two parts. This transformation does not alter the radius of the edges. These parts are rotated along a circle formed by three points. It is recommended for global length errors. Rotation Center Daniel Görsch 22. 11. 2020 Carl Zeiss © 2003 13
Carl Zeiss IMT Blade. Pro Best Fit Transformations – Shift Elongation The points of the edge profile are shifted along a projection line. Transformed Edge Profile The shifting value is the same for all points. Projection Center Original Edge Profile This transformation alters the radius of the edges. It is recommended for local length errors at the profile edges. Daniel Görsch 22. 11. 2020 Carl Zeiss © 2003 14
