Abstract

Tema ovog diplomskog rada je projektiranje naprave za stezanje složenog dijela kod obrade na numerički upravljanoj glodalici. Stezna naprava koristila bi se u tvrtki Eko Međimurje d.d. za smanjivanje pomoćnih vremena obrade čime bi se povećala iskoristivost i produktivnost numerički upravljane glodalice. Prvi, uvodni dio opisuje što je uopće proizvodnja i kako se proizvodnja razvila do ove današnje. Nadalje, drugi dio opisuje obradu odvajanjem. Njezin povijesni razvoj, osnovnu podjelu, vrste gibanja, osnovne elemente alata i njihov materijal. Dalje govori o trošenju oštrice reznih alata i na kraju o određivanju parametara obrade i podjeli alatnih strojeva. Treći dio ovog rada govori o reznim alatima, standardnim držačima alata i napravama za stezanje obratka. Četvrti dio opisuje tvrtku Eko Međimurje d.d., njihove proizvodne procese, nabrojeni su strojevi i oprema koju koriste i detaljno je opisan proizvodni proces za obradu na 5-osnoj numerički upravljanoj glodalici. Peti dio odnosi se na projektiranje stezne naprave, analize dobivenog nacrta, izrade 3D modela, tehničke dokumentacije i tehnološkog procesa izrade dijelova naprave i popisa potrebnih alata i njihovih režima obrade. Potrebna tehnička dokumentacija za dijelove stezne naprave izrađena je u programu DS Catia

Abstract (english)

The theme of this diploma work is design of a clamping device for machining of complex part on a numerically controlled milling machine. The clamping device would be used in company Eko Međimurje d.d. to reduce auxiliary processing time which would lead to increasing usability and productivity of numerically controlled milling machine. The first introductory part describes what production is all about and how production has developed to those of today. Furthermore, the second part describes the material-removal process. Its historical development, basic division, type of motion, basic tool elements and their material, cutting tool consumption and finally the determination of machining parameters and basic division of machine tool. The third part of this work deals with cutting tools, standard tool holders and clamping devices. The fourth part describes the company Eko Međimurje d.d., their production processes, list of the machines and equipment they are using and detailly described the manufacturing process for machining on a 5-axis numerically controlled milling machine. The fifth part refers to the design of the clamping device, analysis of drawn draft, designing of 3D model, the technical documentation and the technological process of making parts of clamping device and the list of necessary tools and their processing regimes. The required technical documentation for the parts of the clamping device was made in the program DS Catia.
