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