Modeliranje obdelave z abrazivnim vodnim curkom = [Modeling of abrasive water jet cutting processes] : doktorsko delo
Lebar, Andrej, strojnik
Obdelava z abrazivnim vodnim curkom (AVC) je nekonvencionalni postopek obdelave materialov. Spada v skupino postopkov z usmerjenim dovajanjem energije. Prednost obdelave z AVC pred sorodnimi postopki ...je v tem, da ne povzroča toplotno prizadete cone. Z AVC lahko obdelujemo širok spekter materialov, tako kovinskih kot tudi nekovinskih. Najpogosteje AVC uporabimo za razrez materialov. Slabost obdelave z AVC pri rezanju materialov je, da na obdelovancu pušča brazdavo površino, in konične stene reza. Napovedovanje rezultatov procesa obdelave z AVC je še na izkustvenem nivoju, zato si prizadevamo razviti modele, ki bi dobro popisali proces obdelave z AVC. V delu smo predstavili nov pristop k modeliranju obdelave z AVC. Naš model temelji na osnovi enotskega dogodka procesa, ki je v tem primeru udarec abrazivnega zrna. Izmerili smo geometrijske značilnosti enotskega dogodka, tako da smo realni proces nadomestili s fizikalnim modelom procesa. Izmerjene odvisnosti smo vnesli v simulacijo, ki temelji na predlaganem modelu. Rezultati simulacije je virtualna površina obdelovanca.
