20.500.12556/RUL-107421 Strategija obdelave s potopno elektroerozijo za doseganje majhne obrabe elektrode Die-sink electrical discharge machining strategy for achieving low electrode wear Delo obravnava problem obrabe grafitnih elektrod pri izdelavi utorov s potopno elektroerozijo. Izdelava utora pogosto zahteva dolgo in neugodno oblikovano elektrodo, ki poleg slabega izpiranja reže v utoru privede do prekomernega obrabljanja elektrode. Določimo tri strategije z različnimi kombinacijami parametrov obdelave in izdelamo potrebno število elektrod. Oblikujemo obdelovanec, na katerem ponazorimo izdelavo utorov iz prakse. Na koordinatnem merilnem stroju izmerimo elektrode, izvedemo obdelavo in ponovno izmerimo elektrode. Razlika v meritvah in vizualni pregled nam vrne vpogled na najprimernejšo kombinacijo parametrov potopne elektroerozije. Thesis deals with the problem of wear of graphite electrodes in manufacturing grooves with die-sink electroerosion. Manufacturing a groove often requires a long and unfavorably shaped electrode, which in addition to poor rinsing of the slot in the groove leads to excessive wear of the electrode. Three strategies with different combinations of processing parameters are defined and required number of electrodes is produced. Workpiece that illustrates the production of grooves from practice is designed. On the coordinate measuring machine we measure the electrodes, manufacture grooves and remeasure the electrodes. The difference in measurements and the visual inspection gives us insight into the most suitable combination of parameters of die-sink electroerosion. potopna elektroerozija obraba elektroda grafit utor die-sink electrical discharge machining wear electrode graphite groove true false false [A.
