Influence of the Coated Carbide Grade on the Cutting Tool Life When Machining Inconel 718

Abstract:

This article deals with the machining of Inconel 718 alloy. In the research, several carbide milling tools with different carbide grades and coatings were used. The main aim is compare all cutting tools in terms of their cutting tool life during machining super alloy Inconel 718. This material is used for highly stressed components in the nuclear industry, such as combustion turbine. Due to its rapid hardening and high heat generation, it is very problematic to machining. The right choice of appropriate carbide grade is necessary to achieve high-quality cutting wedge, which is important for good adhesion of the coating. The results of this work will be used for further research and development of cutting tools for machining Inconel 718.
