This paper contributes to broadening the knowledge regarding cutting tool wear in the finish turning operations of nickel-chromium-based superalloy Inconel 718. Three cutting tools coated with heat isolating TiAIN/A1TiN layers with different stoichiometry ratios recommended as specially designed cutting tools for aerospace industry applications are tested. The primary comparison of tool wear resistance was based on the wear curves related to the cutting time and the removed material volume. The basic study include the modeling of wear progress and examining tool wear scars based on SME images and EDX analysis. In addition, tool wear progress was recorded along with continuous measurements of cutting forces and determination of relevant amount of the specific cutting energy and the friction coefficient.
