Abstract
V magistrskem delu ovrednotimo konstrukcijsko obliko usmerjevalnega vložka, ki jo uporabimo za čim bolj enakomerno obdelavo orodnih vložkov, kjer se obdelava izvaja z abrazivnim tokom. V teoretičnem delu najprej opišemo različne osnovne tehnologije 3D tiska in polimerni filament Onyx. V nadaljevanju predstavimo še proces obdelave z abrazivnim tokom (AFM) in kontaktni ter 3D optični merilnik, ki ju uporabimo za potrebe spremljanja topografije površine in ovrednotenja rezultatov. V eksperimentalnem delu smo opravili več različnih preizkusov, kjer smo obdelavo orodnih vložkov z abrazivnim tokom analizirali s pomočjo kontaktnega merilnika. Na podlagi rezultatov smo prilagajali konstrukcijsko obliko 3D tiskanega usmerjevalnega vložka za dosego čim bolj enakomerne obdelave površine. Pri končnem orodnem vložku se je primerjala tudi stopnja obrabe in hrapavost po površini s pomočjo 3D optičnega merilnika. Izvedena je bila tudi stroškovna analiza med ročnim in strojnim poliranjem orodnega vložka. Delo prikazuje, da se lahko z uporabo usmerjevalnega vložka pri abrazivni obdelavi zagotovi skoraj enakomerno obdelavo po celotni površini orodnega vložka. Doseže se tudi bistveno krajši čas poliranja, kar vpliva na končno ceno izdelka.

Title:
Optimising of machine polishing process using oriented inserts
Abstract:
In the master thesis, we evaluate the design of a oriented insert used for the processing of tool inserts, where the machining is carried out with an abrasive flow. In the theoretical part, we first describe the different basic 3D printing technologies and the Onyx polymer filament. We then go on to present the abrasive flow machining (AFM) process and equipment used to measure the surface topography. In the experimental part, several different experiments were carried out where the abrasive flow machining of tool inserts was analysed using the contact gauge. Based on the results, the design of the 3D printed oriented insert was adjusted to achieve the most uniform surface treatment. The final tool insert was also compared for wear rate and roughness across the surface using a 3D optical measuring equipment. A cost analysis between manual and machine polishing of the tool insert was also carried out. In this work we show that the use of a oriented insert in abrasive machining can provide almost uniform machining over the entire surface of the tool insert. A significantly shorter polishing time is also achieved, which has an impact on the final cost of the product.
