Abstract
V diplomski nalogi je predstavljena analiza vpliva pulzirajočega načina dovajanja hladilno mazalnega sredstva pri struženju titanove zlitine Ti6Al4V. Težko obdelovalni materiali (med katere sodi tudi titanova zlitina Ti6Al4V) zaradi svoje trdote, trdnosti in nizke toplotne prevodnosti povzročajo težave pri procesih odrezavanja. Ena od težav je tvorjenje dolgih odrezkov, s ciljem kontroliranega tvorjenja odrezkov je bil v Laboratoriju za odrezavanje razvit sistem za pulzirajoče dovajanje hladilno mazalne tekočine. Namen naloge je bil analizirati vpliv pulzirajoče asistence HMT na tvorjenje odrezkov, porabo energije in porabo hladilno mazalne emulzije ter izvesti primerjavo s klasičnim nizkotlačnim in visokotlačnim dovajanjem HMT. Rezultati so pokazali, da je tak način dovajanja hladilno mazalnega sredstva lahko dobra alternativa visokotlačnemu dovodu, saj je poraba energije bistveno manjša, prav tako so manjši pretoki hladilno mazalnega sredstva, hkrati pa imamo popoln nadzor nad tvorjenjem odrezkov.

Secondary title: |
Analysis of the influence of the pulsating high pressure coolant supply when turning titanium alloy Ti6Al4V |
Secondary abstract: |
This thesis analyses effects of pulsating high pressure supply of coolant when turning titanium alloy Ti6Al4V on CNC lathe on the machinig process itself. Materials, which are harder to machine (among them titanium alloys), cause problems in cutting processes, due to their hardness, strength and low thermal conductivity. One of the problems is the formation of long chips. With the aim of controlling the formation of chips, a pulsating high pressure coolant supply system was developed at the Laboratory for machining. The purpose of this assignment was to analyse the influence of pulse assisted cooling on chips formation, validate energy consumption and cutting fluid flow rates and to compare the system to the more traditional low pressure an high-pressure coolant delivery systems. The results showed that pulsating high pressure coolant supply is a good alternative to highpressure delivery of coolant, because energy consumption as well as flow can be significantly lower, while at the same time we obtain complete control on the formation of chips. |
