GEOMETRICAL DEVIATIONS MEASUREMENT UNCERTAINTY ESTIMATION USING RANDOM FUNCTION

Edi Kulderknup, Argo Pandis
Abstract:
Workpiece geometrical deviations have essential influence for quality of apparatus. Geometrical deviations of apparatus mechanical components have accuracy level better as 1 µm.
For apparatus mechanical parts are used widely limits for flatness, cylindricity and position. By measurements of them shall be taken account additionally factors like autocorrelation between measurement points and influence factors variation over measurement area. Last can be described as random function which gives ground for the model of measurement and uncertainty estimation.
