20.500.12556/DKUM-14495 Integracija laserskega interferometra in koordinatne merilne naprave v merilni sistem za merjenje dimenzij INTEGRATION OF A LASER INTERFEROMETER AND A COORDINATE MEASURING MACHINE INTO A MEASUREMENT SYSTEM FOR CALIBRATING DIMENSIONAL QUANTITIES Merjenje dimenzij se je v Laboratoriju za tehnološke meritve do nedavnega izvajalo na univerzalnemu merilniku dolžin Zeiss 01-660C, kateri ima velike prispevke k merilni negotovosti, le teh pa ni mogoče zmanjšati. Zato smo se odločili, da preučimo možnost izdelave kalibracijskega postopka na trikoordinatni merilni napravi (KMN) z absolutno sledljivostjo na primarni etalon preko laserskega interferometra (LI). Pri metodah raziskovanja smo integrirali KMN in LI v en merilni sistem, izdelali postopek merjenja, preizkusili ponovljivost na integriranem merilnem sistemu, določili vplivne parametre na meritev, eksperimentalno določili koeficient za merjenje notranjih in koeficient za merjenje zunanjih dimenzij, ocenili skupno merilno negotovost in potrdili ovrednoteno merilno negotovost na različnih umerjenih etalonih. Za merjence npr dolžine 100 mm smo napram prejšnjem postopku meritve zmanjšali merilno negotovost za 77%, za merjence dolžine 1000 mm pa kar za 82%. Razvili smo matematični model meritve in izvedli celovito analizo merilne negotovosti za integriran sistem LI in KMN. S postopkom nameravamo sodelovati v mednarodnih interkomparacijah, kot osnovnemu orodju za potrditev znanstvenih tez v meroslovju, in tako potrditvi ovrednoteno merilno negotovost. Until recently the dimension measurement has been done in the Laboratory for technological measurement by a Universal length meter Zeiss 01-660 C. This fact contributed a lot to the measurement uncertainty, but it could not be reduced. This is why we decided to examine the possibility of developing and building a calibration procedure on a three-coordinate measurement device (CMM) with absolute traceability on primar standard with laser interferometer (LI). Using the research methods we integrated CMM and LI into one measurement system, designed the measurement procedure, tested its repeatability, set the influential parameters into the measurement, experimentally defined a coefficient for measurement of external and coefficient of internal dimensions and evaluated the overall measurement uncertainty on various calibrated standards. As the result we achieved a reduction of measurement uncertainty on 100 mm long samples for 77% and on 1000 mm long samples for 82%. We developed a mathematical measurement model and performed a wholesome analysis of the measurement uncertainty for the integrated systems LI and CMM. With this procedure we intend to take part in and cooperate with international intercomparisons as a basic tool for confirmation of scientific thesis in metrology and consequently confirm the evaluated measurement uncertainty. merjenje dimenzij koordinatna merilna naprava laserski interferometer notranje dimenzije zunanje dimenzije integriran sistem merilna negotovost. dimensional quantities Coordinate Measuring Machine Laser Interferometer internal dimensions external dimensions integrated system measurement uncertainty true true false T.
