Abstract

Trokoordinatni mjerni strojevi - CMM (eng. coordinate-measuring machine) strojevi koriste se u različitim industrijama poput automobilske, zrakoplovne, medicinske, strojogradnje i mnogih drugih. Njihova primarna svrha je pružiti precizne i točne mjere koje se koriste za kontrolu kvalitete i analizu proizvoda. Ukoliko dođe do pogrešaka u mjerenju, sama kontrola proizvoda nije primjenjiva te nije moguće napraviti kvalitetnu analizu proizvoda.
Kako se mjerenja provode pomicanjem sonde duž predmetovih površina ili točkastim dodirivanjem određenih točaka, ukoliko dođe to trošenja vrha sonde ili mjerne površine doći će i do pogrešaka u samim mjerama.
U ovom radu su opisani principi rada trokoordinatnih mjernih uređaja s dodirnim sustavom za akviziciju mjernih točaka, predložen je mjerni postav kojim se može ispitati utjecaj odabranih ticala na točnost rezultata mjerenja te su prikazani prikupljeni podaci.

Abstract (english)

Coordinate-measuring machine (CMM) machines are used in various industries such as automotive, aerospace, medical, mechanical engineering, and many others. Their primary purpose is to provide precise and accurate measurements used for quality control and product analysis. If errors occur in the measurements, product control is not applicable, and it is not possible to perform a quality product analysis.
Measurements are carried out by moving the probe along the surfaces of the objects or by point contact with specific points. If there is wear on the probe tip or measuring surface, errors in measurements will occur.
This paper describes the principles of operation of three-coordinate measuring devices with a touch system for acquiring measurement points. A measurement setup is proposed to investigate the influence of selected styli on the accuracy of measurement results, and the collected data is presented.
