| Sažetak | Ovim radom opisana je problematika odabira materijala i tehnološkog postupka kojim je moguće proizvesti alatna kolica, detaljno su opisana ispitivanja i analizirani dobiveni rezultati. Izrada alatnih kolica zahtjeva niz koraka prije proizvodnje, a to su razna ispitivanja materijala (kemijski sastav, tvrdoća, čvrstoća, metalografska analiza), usporedba dobivenih rezultata, odabir odgovarajućeg materijala i tehnološkog postupka, izrada modela, izrada tehničkih nacrta te simulacija ispitivanja sklopa. Laboratorijska ispitivanja materijala provedena su u Centru za istraživanje materijala u Puli (METRIS). Od važnijih metoda korištenih za potrebe ovoga rada valja istaknuti metodu analize, metodu dokazivanja, matematičku metodu, eksperimentalnu metodu, metodu mjerenja i modeliranja. Za potrebe ovoga rada testirano je pet različitih limova, materijala DC01 (debljine 1 i 2 milimetra), DC03 (debljine 1 i 2 milimetra) i S235JR+AR (debljine 2 milimetra). Provedeni rezultati ispitivanja upućuju da je najbolji materijal za izradu alatnih kolica čelik S235JR+AR koji ujedno najbolje odgovara tehnološkom postupku izrade alatnih kolica, stoga je odabran kao prikladan materijal za izradu. Nakon odabira materijala pristupljeno je izradi dijelova alatnih kolica koristeći softver Fusion 360 u kojem je izrađen sklop koji je statički ispitan u svrhu dokazivanja konačne nosivosti. Koristeći Fusion 360 ujedno je izrađena simulacija rezanja police alatnih kolica koja kao rezultat ispisuje G-kod koji može upravljati CNC strojem. |
| Sažetak (engleski) | This thesis describes the issues related to the selection of materials and the technological process for producing tool carts, detailing the tests conducted and analyzing the results obtained. The production of tool carts involves several steps prior to production, including various material tests (chemical composition, hardness, strength, metallographic analysis), comparison of the results, selection of suitable materials and technological processes, model making, preparation of technical drawings, and simulation of assembly tests. Material laboratory testing was conducted at the Materials Research Center in Pula (METRIS). Among the important methods used for this work are analysis method, proof method, mathematical method, experimental method, measurement method, and modeling method. For the purposes of this work, five different sheet metals were tested, materials DC01 (thicknesses of 1 and 2 millimeters), DC03 (thicknesses of 1 and 2 millimeters), and S235JR+AR (thickness of 2 millimeters). The test results indicate that the best material for making tool carts is steel S235JR+AR, which also best suits the technological process of manufacturing tool carts, and therefore it was selected as the suitable material for production. After selecting the material, parts of the tool carts were made using Fusion 360 software, where an assembly was created and statically tested to demonstrate its final load-bearing capacity. Additionally, using Fusion 360, a simulation of cutting the shelves of the tool carts was performed, resulting in the generation of G-code that can control a CNC machine. |
