INFLUENCE OF MATERIAL CHEMICAL COMPOSITION OF CUTTING TOOLS AND CUTTING PARAMETERS ON THE WEAR OF CUTTING TOOLS OF THE CARBIDE METALS

Ovim radom analiziran je utjecaj sastava materijala rezenog alata i parametara obrade na trošenje reznog alata od tvrdog metala. Završni rad sastoji se od teorijskog (općeg) i eksperimentalnog dijela. Općim (teorijskim) dijelom opisani su tvrdi metali, njihovo dobivanje i primjena, također su obuhvaćeni rezni alati sa posebnim naglaskom na glodala. U eksperimentalnom dijelu opisan je proces izrade reznih alata od tvrdih metala te njihovo trošenje s obzirom na različiti kemijski sastav te određene parametre obrade. Eksperimentalni dio diplomskog rada odrađen je u tvrtci Niteh d.o.o. Nakon završetka eksperimentalnog dijela rada napravljena je analiza rezultata te na temelju istih donesen zaključak.This paper analyzes the influence of the material composition of the cut tool and machining parameters on the wear of the carbide cutting tool. Thesis consists of a theoretical (general) and an experimental part. The general (theoretical) part describes carbide metals, their production and application, cutting tools with special emphasis on milling. The experimental part describes the process of making cutting tools from hard metals and their wear with regard to different chemical composition and certain processing parameters. The experimental part of the thesis was done in the company Niteh d.o.o. After the completion of the experimental part of the work, an analysis of the results was made and a conclusion was made based on them
