20.500.12556/DKUM-91550 Sprememba tehnologije obdelave gravurnega vložka - čepa diplomsko delo Change in the technology of processing of the engraving insert - plug Diplomsko delo obravnava spremembo tehnologije obdelave gravurnega vložka – čepa v podjetju Unior, d. d., kjer smo analizirali trenutno in novo tehnologijo izdelave. Cilj dela je bil ugotoviti, ali nova tehnologija prinaša izboljšave v času izdelave, porabi materiala in kakovosti obdelave. V delu so predstavljeni postopki struženja in kovanja, vloga čepa v utopu in izziv trenutne tehnologije, ki zahteva dvojno vpetje obdelovanca, kar povzroča odstopanje cilindričnosti. Analiza je pokazala, da nova tehnologija omogoča prihranek časa za skoraj 60 minut pri izdelavi 20 čepov. Po drugi strani pa nova tehnologija porabi več materiala, kar vpliva na stroške. Diplomsko delo ponuja poglobljeno primerjavo obeh tehnologij in vključuje ključne parametre, kot so čas izdelave, poraba materiala in kakovost izdelave, kar omogoča boljšo odločitev glede prihodnje izbire tehnologije. The thesis addresses the change in the technology of processing the engraving insert – the plug, at the company Unior d.d., where both the current and new manufacturing technologies were analyzed. The aim of the thesis was to determine whether the new technology offers improvements in production time, material consumption, and processing quality. The thesis presents the turning and forging processes, the role of the plug in the tool, and the challenge of the current technology, which requires double clamping of the workpiece, causing deviations in cylindricity. The analysis showed that the new technology allows a time saving of almost 60 minutes when producing 20 plugs. On the other hand, the new technology consumes more material, which affects the costs. The thesis offers an in-depth comparison of both technologies and includes key parameters such as production time, material consumption, and product quality, which enables a better decision regarding the future choice of technology.
