Abstract:	Vsako sodobno podjetje želi biti v koraku s časom, biti uspešno, učinkovito, sodobno organizirano, dosegati najboljše rezultate v smislu kvalitete, stroškov in dobavnih rokov ter biti produktivno. Za vse to je pomembno, da se nenehno izboljšujemo in razvijamo. Sam razvoj moramo skrbno premisliti in načrtovati ter celovito obravnavati. Že pri načrtovanju razvoja v osnovnih fazah poslovnih procesov je pomembno, da se osredotočimo na vse morebitne kriterije in faktorje, ki so del celotnega poslovanja. Tako je tudi pri proizvodnem procesu termičnega rezanja, ki smo ga obravnavali v diplomski nalogi. Z raziskavo smo ugotovili, da je treba poleg kriterijev, kot so: vrsta in debelina materiala, rezalna hitrost, kvaliteta obdelave, vpliv na okolje ter stroški, ki smo jih podrobneje analizirali, upoštevati tudi druge dodatne dejavnike, kot so: najpogostejše debeline materialov, ki jih želimo rezati, najpogostejše vrste materialov, ki jih želimo rezati, kakšno kvaliteto rezane površine potrebujemo, kakšen postopek obdelave sledi, kako velike so serije obdelovancev, kakšna bo zasedenost naprave, kakšne zahtevnosti bodo obdelovanci glede na obliko, kako velika naročila so oz. bodo zagotovljena za določene izdelke, kakšna fleksibilnost je zahtevana, kakšne so prostorske omejitve ter zakonske zahteve do okolja. Na osnovi analize osnovnih kriterijev za potrebe rezanja konstrukcijskega jekla, aluminija ter nerjavnega jekla smo ugotovili, da je najbolj primeren način termičnega rezanja rezanje z laserjem. Ko pa smo dejansko upoštevali tudi vse ostale dejavnike in želje potencialne stranke, pa smo prišli do spoznanja, da je najbolj primerna tehnologija rezanja za potencialno podjetje kombinacija plamenskega in plazemskega rezanja. Vedno je treba izbrati tiste rešitve, ki jih bomo v večini primerov tudi izkoristili, zagotovili možnosti za nadaljnji razvoj ter ugodili predpisom o zaščiti okolja.

Title:	Production process renewal for cut materials in the potential company
Abstract:	Every modern enterprise aims to constantly be in step with the state-of-the-art, to be effective, efficient, and organised in a modern fashion, to achieve the best results in terms of quality, cost and delivery times, and be productive. For all this, it is important to constantly improve and develop. However, development must be carefully considered and planned, as well as comprehensively addressed. Already in planning the development of business processes, it is important to focus on all criteria and factors that are part of overall operations. This also applies to the manufacturing process of thermal cutting, which is discussed in the thesis. During the research, we found that it is necessary, in addition to criteria such as the type and thickness of the material, cutting speed, surface quality, environmental impact and costs, which we analysed in detail, to take into account also other additional factors, such as the most common thicknesses of the materials we want cut, the most common types of materials we want to cut, the quality of cut surfaces needed, what treatment processes follow, the size of the batch of workpieces, the device utilisation rate, the complexity of the workpieces with respect to shape, order sizes of certain products, the required flexibility, any spatial limitations and legal requirements relating to the environment. Based on the analysis of the basic criteria for the purpose of cutting structural steel, aluminium and stainless steel, we found that the most suitable method of thermal cutting is laser cutting. However, when we actually took into account all other factors and the wishes of potential customers, we came to the conclusion that the most suitable technology for a potential enterprise is a combination of flame and plasma cutting. Those solutions that provide opportunities for further development and comply with the regulations governing environmental protection should always be - and most often will be - chosen.
