<p>Koordinatne merne mašine (KMM) su dominantni merni instrumenti u<br />dimenzionalnoj metrologiji. NJihovom upotrebom se može izmeriti<br />bilo koja makro tolerancija označena na tehničkoj dokumentaciji.<br />Tolerancija ravnosti je često prisutna u cilju izvršenja zahtevanih<br />funkcionalnih zahteva radnog predmeta. Istraživanja sprovedena u<br />ovom radu se bave problemom procene greške ravnosti merene na KMM<br />zasnovane na metodi minimalne zone i procene merne nesigurnosti za<br />ovaj merni zadakat. Aksenat je stavljen na primeni Monte Karlo<br />metode kao simulacionog alata za procenu merne nesigurnosti.<br />Razvijena je nova metodologija za procenu greške ravnosti kao i<br />simulacioni model za procenu merne nesigurnosti za ovaj merni<br />zadatak.</p> / <p>Coordinate measuring machines (CMMs) are dominant measuring<br />instruments in dimensional metrology. These machines can measure any<br />macro-tolerance indicated in the technical documentation. Flatness tolerance<br />is often present with the aim of completing the needed functional<br />requirements of a workpiece. The investigation conducted in this paper<br />considers the problem of assessing the flatness error measured on a CMM<br />based on the minimum zone method and on the method of evaluating<br />measurement uncertainty for this measuring task. The emphasis is on the<br />use of Monte Carlo method as a simulation tool for evaluating measurement<br />uncertainty. A new methodology for assessing the flatness error has been<br />developed, as well as a simulation model for evaluating measurement<br />uncertainty for this measuring task.</p>
