20.500.12556/RUL-130030 Uporaba tehnologije 3D skeniranja v orodjarstvu Usage of 3D scanning technology in tool making industry Pri brizganju plastike se v fazi ohlajanja srečujemo s problemom deformacij plastičnega izdelka. Problem lahko rešujemo s prilagajanjem parametrov brizganja, vendar v večini primerov deformacij ne moremo v popolnosti odpraviti. Zato poleg uporabe idea1nih parametrov, preoblikujemo gravuro orodja v nasprotno smer deformacije plastičnega kosa in tako zagotovimo ustrezno obliko končnega izdelka. Za uspešno korekcijo orodja je najprej potrebno izmeriti deformacijo plastičnega izdelka, za kar se je prej v podjetju uporabljal koordinatni merilni stroj, tekom te diplomske naloge pa je predstavljena uporaba 3D skenerja. Poleg merjenja je prikazana tudi korekcija orodja v CAD okolju in nato fizična izdelava modifikacij. V zaključku so prikazani rezultati, ki potrjujejo, da je uporaba 3D skeniranja primerna za mersko korekcijo orodja, saj smo v samo enem krogu korekcij vse korigirane pozicije pomaknili znotraj tolerančnega območja. When injecting plastic, in the cooling phase we encounter the problem of deformation of the plastic piece. The problem can be solved by adjusting the injection parameters, but in most cases the deformation cannot be completely eliminated. Therefore, in addition to using the ideal parameters, we modify the engraving of the tool in the opposite direction of the deformation of the plastic piece and thus ensure the appropriate shape of the final product. For successful tool correction, it is first necessary to measure the deformations of the plastic piece. In the past, a coordinate measuring machine was used. In this diploma thesis the use of a 3D scanner is presented. In addition to the measurements, the correction of the tool in CAD environment and then the physical modifications is also shown. The conclusion shows results that confirm that the use of 3D scanning is suitable for dimensional correction of plastic injection tools. After all, in one round of corrections, we moved all the measured positions within the tolerance range. 3D skeniranje 3D digitalizacija brizganje plastike korekcija orodja za tlačno brizganje kontrola brizganih kosov 3D scanning 3D digitization injection molding correction of injection molding tools control of injection molded pieces true false false [A.
