- Abstract:
- This paper examines the possibility to set up standardized sampling strategies for circular features, which are tolerated according to the international system of limits and fits. The measuring process is simulated by a mathematical model and the sampling strategy derived for various measurement conditions. One important aim of the proposed model is to control the measurement uncertainty of the measurement process within certain limits of the feature tolerance. To do so the measurement uncertainty is esti-mated according to international standards. The model of the estimation process considers as uncertainty contributors the coordinate measuring machine, environmental conditions and workpiece deviations. Simulations have shown that it is possible to derive standardized sampling strategies for circular features tolerated according to the ISO system of limits and fits if measurement process parameters are classified.
