Abstract
U ovom diplomskom radu opisani su mjerni valjčići zajedno sa njihovim značajkama i primjenom korištenja kao što je metoda s tri valjčića. Prema normi ISO 16239:2013, Mjerni valjčići za mjerenje metričnih vijčanih navoja navedeni su zahtjevi na materijal mjernih valjčića, vrijednost nazivnih promjera i tolerancije promjera. Također je detaljno razrađen postupak umjeravanja mjernih valjčića. Proveden je postupak mjerenja promjera odabranih mjernih valjčića prema normi ISO 16239:2013 u Laboratoriju za precizna mjerenja dužina koji djeluje kao Nacionalni laboratorij za duljinu u Republici Hrvatskoj. Opisana je i procijenjena mjerna nesigurnost pomoću rezultata mjerenja pri čemu je provedena i Monte Carlo simulacija za provjeru proračuna mjerne nesigurnosti koja je također ukratko opisana u ovome radu. Za kraj je provedena usporedba rezultata mjerenja sa tolerancijama norme kako bi se ustanovilo da li mjerni valjčići zadovoljavaju postavljene kriterije te je donesen zaključak.
Abstract (english)
In this master thesis measuring pins are described together with their features and applications such as the three wire method. According to ISO 16239:2013, Metric series wires for measuring screw threads requirements of material, nominal diameter values and diameter tolerances are defined for measuring pins. The calibrations procedure of the measuring pins has also been elaborated in detail. According to ISO 16239:2013 measurements of the diameter of selected pins was carried out in the Laboratory for precise measurement of length acting as the National laboratory for length in the Republic of Croatia. Measuring uncertainty is described and estimated by values of measurements. Monte Carlo simulation is also described in this paper and used to check the calculation of uncertainty. At end, a comparison of measurement results and norm tolerances is carried out to conclude if measuring pins meet the set criteria
