zaključna naloga Razvojno raziskovalnega programa I. stopnje Strojništvo
Abstract
V tej zaključni nalogi je predstavljen vpliv visokotlačnega pulzirajočega dovajanja hladilno mazalne tekočine (HMT) pri procesu struženja na nastanek odrezka pri obdelavi super zlitine. Eksperimente smo opravili na titanovi zlitini, saj so v industriji zahteve po uporabi teh materialov vse večje. V okviru naloge smo se bolj osredotočili na fino obdelavo, saj je pri finih parametrih struženja lomljenje odrezkov najbolj težavno. Ugotovili smo, da med parametri visokotlačnega pulziranja s HMT, parametri struženja in dimenzijami deformacije odrezka ni opaznih povezav. Pri drugem eksperimentu so rezultati pokazali, da s pomočjo visokotlačnega pulzirajočega dovajanja HMT v rezalno cono dobimo bolj ugodne odrezke kot pri visokotlačnem dovajanju HMT. Nazadnje pa smo pokazali še, da je bolj ugodno imeti veliko podajanje in majhno globino rezanja struženja, saj se odrezki lomijo pri nižjih tlakih.

Secondary title: |
Analysis of high pressure pulsating cooling lubrication fluid influence on chip formation in turning process |
Secondary abstract: |
In this thesis we present the effects of high pressure pulsating cooling lubrication fluid (CLF) influence on chip formation in turning process of super alloys. We chose to conduct our experiments with titan alloy because super alloys are very desired in industry. The most visible effect is when we use small feed rate and shallow cutting depth because it is hard to brake chips with these cutting parameters. Results showed that there is no distinctive correlation between turning, high pressure pulsating parameters and the area of deformation of the chips. With the use of high pressure pulsating CLF we managed to achieve better and more suitable chips than with the high pressure system that does not use the pulsating method. Lastly we proved that it is better to have big feed rate and shallow cutting depth than vice versa because in that case chips can be broken at lower supplying pressure of CLF. |
