Modern quality control has become unthinkable without optical measuring systems which are intensively used in automotive industry. This paper shows the analysis of preparation of models in terms of proper positioning in relation to the digitized model and the correct interpretation of the results of quality control. Experimental results verifying the method and the theory are shown. Part of tool for pressing and fabricated physical model of passenger car's suspension control arm is compared to

KEY WORDS: 3D digitizing, Triangulation, Registration, Inspection, CAD/CAM/CAE REGISTRACIJA I INSPEKCIJA POVRŠINA AUTOMOBILSKIH OTPRESAKA ZASNOVANA NA OBLAKU TAČAKA KOJI GENERIŠU OPTIČKI MERNI SISTEMI REZIME: Savremena kontrola kvaliteta je postala nezamisliva bez optičkih mernih uređaja koji se intenzivno koriste u automobilskoj industriji. U ovom radu prikazana je analiza pripreme modela u pogledu pravilnog pozicioniranja u odnosu na digitalizovani model i tačna interpretacija rezultata kontrole kvaliteta. Eksperimentalni rezultati koji verifikuju metodu i teoriju su prikazani. Deo alata prese i njime izrađeno ocsilujuće rame su upoređeni sa CAD modelom. Prikazani rezultati merenja pokazuju da su optički merni sistemi moćan alat za kontrolu kvaliteta, analizu i otkrivanje uzroka grešaka.
