CNC PLASMA CUTTING MACHINE

U radu je analizirano rezanje plazmom. Prikazan je teorijski pristup ovome sve prisutnome načinu rezanja, počevši od njegovog začetka do danas. Kao vrijeme nastanka tj. početka primjene rezanja plazmom uzimaju se 1950.-e godine. Ono što je isključivo važno naglasiti jest sve što plazma rezanje nudi, a upravo je to ono zbog čega se već više od 50 godina neprestano razvija i koristi. Suvremeni pristup plazma rezanju podrazumijeva mogućnost integracije s izvorom energije, CNC sustave, kao i automatizaciju, što dovodi do preciznog, brzog i povoljnog obrađivanja materijala, odnosno njegovog rezanja. Obzirom da plazma rezanje zadržava svoju prvobitnu svrhu, a pri tome se danas koristi s brojnim poboljšanjima, prikazan je povijesni razvoj te kako se koristila na samome početku. Isto tako, naglašene su prednosti zbog kojih se koristi, ali su izdvojeni i nedostaci koje susrećemo prilikom rezanja. Opisan je suvremeni pristup plazma rezanju, način na koji se koristi te ono što ga obilježava danas. Odabran je i prikazan uređaj plazma rezanja Hypertherm Powermax105®, koji se primjenjuje prilikom rezanja do 32 mm debljine, a nudi najnovije tehnološke inovacije kao što su Smart Sense™ za automatsko podešavanje tlaka plina te 7 tipova Duramax™ pištolja za različite primjene. Kao i uvijek u proizvodnji uzimaju u obzir se uzima sve ono što dolazi sa samim uređajem, a upravo zato je prikazan način primjene te što ga obilježava. Prikazana je i konstrukcija stola za edukacijsku CNC plazma rezačicu s odgovarajućim tehničkim crtežima i 3D modelima.Plasma cutting was analyzed in this paper. A theoretical approach to this ubiquitous way of cutting is presented, starting from its inception to the present day. Plasma cutting is taken as the time of origin, ie the beginning of the application of plasma cutting. What is extremely important to emphasize is everything that plasma cutting has to offer, and that is exactly why it has been constantly developed and used for more than 50 years. The modern approach to plasma cutting implies the possibility of integration with the energy source, CNC systems, as well as automation, which leads to precise, fast and cost-effective processing of the material, ie its cutting. Since plasma cutting retains its original purpose, and is used today with numerous improvements, the historical development and how it was used at the very beginning is shown. Also, the advantages due to which it is used are emphasized, but the disadvantages we encounter when cutting are also highlighted. The modern approach to plasma cutting, the way it is used and what characterizes it today are described. The Hypertherm Powermax105® plasma cutting device, selected for cutting up to 32 mm thick materials, has been selected and shown, offering the latest technological innovations such as Smart Sense for automatic gas pressure adjustment and 7 types of Duramax pistols for various applications. As always in production, everything that comes with the device itself is taken into account, and that is exactly why the method of application and what characterizes it is shown. The construction of a table for an educational CNC plasma cutter with appropriate technical drawings and 3D models is also shown
