20.500.12556/RUL-124670 Vpliv izdelave luknje na silo vtiskovanja The influence of the hole making process on the embossing force Diplomska naloga obravnava vpliv izdelave luknje na silo vtiskovanja zatičev v obdelano luknjo ulitka. Analiziran je vpliv uporabe različnih kombinacij vrste in koncentracije emulzije pri vrtanju ter pralnega sredstva pri pranju. V okviru diplomske naloge so obravnavane teoretične osnove kakovosti ter vrtanja in pranja. Pri praktičnem delu se je pri vrtanju lukenj uporabila emulzija dveh različnih proizvajalcev. Vsaka se je testirala pri treh različnih koncentracijah. Za pranje vzorcev sta se uporabljali dve različni pralni sredstvi pri isti koncentraciji ter enakih pogojih. V izdelane vzorce se je s pomočjo tlačnega mehanskega testa vtiskovalo zatiče ter spremljalo silo vtiskovanja. Za vsako kombinacijo vrste emulzije in njene koncentracije ter pralnega sredstva je izmerjena srednja vrednost sile vtiskovanja. Na osnovi tega je ugotovljeno, katera kombinacija emulzije in pralnega sredstva nam da najvišjo silo vtiskovanja. The diploma thesis deals with the influence of the hole making process on the force with which pins are embossed into the casting hole. The subject of analysis is the influence of using different combinations of emulsion types and concentrations when drilling, as well as different washing agents during washing. The theoretical framework of the thesis provides basic information with regard to quality and the drilling and washing processes. Thereafter the empirical research showcases the use of two emulsions from different manufacturers during hole drilling. Each emulsion was tested using three different concentration levels. Two different washing agents were used to wash the samples, having the same concentration level and being used in the same conditions. Pins were embossed into the samples by means of a pressure mechanical test, with the embossing force being observed the entire time. The average embossing force was measured for every combination of the emulsion type, its concentration level and the washing agent used. The results show which emulsion and washing agent combine for the highest embossing force. koncentracija emulzije vrtanje pranje tlačni mehanski testi kakovost emulsion concentration drilling washing pressure mechanical tests quality true false false [G.
