Ovim se radom ukazuju prednosti koje pruža visokobrzinska obrada u odnosu na konevkionalnu obradu, te prednosti trohoidnog načina glodanja u odnosu na konvekiconalan način glodanja. Visokobrzinka obrada jedna je od modernih tehnologija koja, u usporedbi s konvencionalnim postupcima, daje veću točnost, učinkovitost i kvalitetu izradaka uz istovremeno smanjenje vremena i troškova obrade. Primjena visokobrzinske obrade nije bila moguća sve do razvitka modernih visokodinamičkih alatnih strojeva. Usporedba konvekcionalne obrade s visokobrzinskom obradom u ovom radu izvršena je na obradi lopatice turbine Inconela 718. Usporedba se vršila pomoću SolidCAM programa gdje su putanje alata za oba načina ista, ali su im parametri obrade drugačiji jer su za visokobrzinsku obradu korišteni alati od ojačane keramike koja omogućuje znatno veće brzine rezanja od tvrdometalnih alata korištenih za konvekcionalni način obrade. Kod usporedbe trohoidnog glodanja s konvekcionalnim glodanjem, korišten je model koji se može izraditi na oba načina. Za predmet koji se izrađuje na stroju izrađena je tehnološka dokumentacija, te je izvršena tehnoekonomska analiza konevkcionalnog i trohoidnog načina glodanja za izrašivani predmet.

This paper points to the benefits provided by high speed machining compared to conventional machining and advantages of trochoidal milling compared to conventional milling. High speed machining is one of the modern technology which in comparison with conventional methods provides greater accuracy and quality of work pieces, better effectiveness while reducing the time and cost of processing. The use of high speed machining was not possible until the development of modern high dynamic machine tools. Comparison conventional machining with high speed machining in this work was done on the machining of turbine blade of Inconel 718. The comparison is carried out using the SolidCAM program where the tool path for both modes are the same, but processing parameters are different for them, because for high speed machining tools were used of reinforced ceramics which allows much higher cutting speeds then the carbide tools used for conventional machining. For comparing trochoidal milling with conventional milling the model which was used can be made in both ways. For object that is machined on the machine technological documentation has been made, and the techno-economic analysis has been made for conevntional and trochoidal milling mode for machined subject.
