Vpliv radija rezalnega robu na sile pri frezanju

Marinšek, Tadej (author), Pušavec, Franci (mentor)

V diplomskem delu se lotevamo problematike vpliva mikrogeometrije frezala na sile pri frezanju. Geometrija rezalnega robu pomembno vpliva na obstojnost orodja, natančnost izdelave in ne nazadnje na rezalne sile. Z ustrezno izbrano geometrijo, materiala in prevleke frezala lahko zagotovimo stabilnost procesa in pripomoremo k bolj optimalnimi ter hitrejši obdelavi. S poznavanjem velikosti sil lahko predvidimo ustrezno vpetje obdelovancev in pripomoremo k izbiri ustreznega orodja za določeno aplikacijo. Pri meritvah rezalnih sil smo spreminjali različne parametre obdelave in s tem dobili spekter analiziranega območja. Variirali smo radialno globino reza in podajanje na zob, kar je posledično pomenilo tudi podajalno hitrost; konstantno smo ohranjali rezalno hitrost in aksialno globino reza. Ugotovili smo, da ima radialna globina reza večji vpliv na velikost sil kot podajalna hitrost in da je pri visoki stopnji odvzema materiala vpliv radija rezalnega robu frezala zanemarljiv.

• Title: Influence of cutting edge radius on cutting forces

Abstract

In this thesis, I research the influence of the milling tool microgeometry on cutting forces. The geometry of the cutting edge significantly affects the durability of the tool, manufacturing accuracy, and cutting forces. With properly selected tool geometry, material, and coating of the tool, we can ensure the stability of the process and contribute to fast and optimal processing. Knowledge of the cutting forces allows us to select the appropriate clamping technique and tools for a particular application. When measuring the cutting forces, we changed different parameters and, thus, obtained the spectrum of the analyzed range of values. We varied the radial depth of cut and feed per tooth, which, consequently, meant also the feed rate while maintaining the cutting speed and axial depth of cut. We concluded that the radial depth of cut has a greater influence on the magnitude of cutting forces than the feed rate and that at a high rate of material removal, the influence of the radius of the cutting edge is negligible.
