20.500.12556/DKUM-84949 Raziskava možnosti skrajševanja nastavitvenih časov na računalniško krmiljenem rezkalnem stroju diplomsko delo Researching the possibilities of reducing setup times on computer-controlled milling machines Tema diplomske naloge izhaja iz podjetja Mark Metal d.o.o. in se nanaša na njihov 3-osni CNC rezkalni stroj Hermle C400, naloga pa je zmanjšati nastavitvene čase. Diplomsko delo predstavlja podroben opis in značilnosti rezkanja, opis vpenjanja in programiranja CNC rezkalnega stroja ter menjavanja orodij. V diplomskem delu sem predstavil tudi vplive in razloge za nastavitvene čase v podjetju. V nadaljevanju sta opisani metodi 5S in SMED. Raziskal sem tudi čase na stroju pred raziskavo, naredil program v Excelu, ki razvršča obdelovance glede na predpisane pogoje. Na koncu diplomskega dela so podani rezultati in ugotovitve raziskave, ter sklep. The topic of the thesis comes from Mark Metal d.o.o. and concerns their Hermle C400 3-axis CNC milling machine, the task is to reduce set-up times. The thesis presents a detailed description and milling characteristics, a desctription of the clamping and programming of the CNC milling machine and tool changing. In the thesis i also present the influences and reason for set-up times in the company. The 5S and SMED methods are described below. I also investigated the times on the machine before the survey, made an Excel program that classifies the workpieces according to the prescribed conditions. At the end of the thesis, the results and findings of the research are given, and a conclusion is drawn.
