Comparison of different interpolation methods, used for modelling of probe heads errors

Virtual CMMs allow user to estimate the uncertainty of measurement using multiple measurement simulations. Most often the Virtual CMMs consist of several modules responsible for main errors sources modelling. These modules utilizes different interpolation methods in order to model the error values i...

Description
Summary:Virtual CMMs allow user to estimate the uncertainty of measurement using multiple measurement simulations. Most often the Virtual CMMs consist of several modules responsible for main errors sources modelling. These modules utilizes different interpolation methods in order to model the error values in any point in machine's measuring volume. Thus the proper functioning of Virtual CMM depends on chosen interpolation method. Experiment described in this paper is aimed to assess which interpolation method would give the best results for newly developed probe head errors model for the articulated probe heads.
