Use of optical measurement system for positioning accuracy testing and geometry verification of the machine tool

Ukoliko želimo odrediti točnost alatnog stroja, potrebno je provesti provjeru točnosti pozicioniranja i provjeru geometrijskih značajki toga stroja. Tradicionalno korišteni uređaji su komparatori, libele, te laserski mjerni sustavi. Posljednjih godina zabilježen je izrazit rast u primjeni tehnologija optičkog 3D skeniranja u svim granama industrije. Tomu je pridonio ubrzani razvoj računalne industrije kao i sve precizniji optički sustavi. Time je omogućena primjena optičkih mjernih sustava u mnogim do sad nekorištenim područjima. U ovom radu dati će se alternativa klasičnom načinu provjere točnosti CNC strojeva uz pomoć 3D digitalizatora tvrtke GOM. U radu će biti opisan način rada sustava, te će se na konkretnom primjeru provjeriti točnost pozicioniranja i geometrijske značajke CNC glodalice uz pomoć 3D digitalizatora.In case when accuracy determination of tooling machine is needed, it is necessary to perform test of positioning of numerically controlled axis as well as geometrical accuracy tests. Traditionally used equipment for this operations are comparators, levels and laser measurement systems. In the past couple of years there have been records of the exponentially increased use of optical 3D scanning technologies in all branches of the industry. These changes have been caused by the rapid development of the computer industry, which has been followed by increased accuracy of optical 3D scanning systems. That way new applications of optical measurement systems have been made possible. In this assignment an alternative way of testing, CNC machine accuracy, using GOM 3D optical measurement equipment will be presented. Along with the explanation of the equipment's function, a series of tests measuring the CNC mill parameters will be performed
