Identification of Technological Parameters when Machining Ni-Alloys by Monolithic Ceramic Milling Tool

Abstract Increasing productivity and usage of hard-to-machine progressive materials are the cause of continual finding of new ways and methods of machining in order to ensure the required quality especially in aviation and aerospace industry. One of these ways is the ceramic milling tool, which combines the pros of conventional ceramic cutting materials and pros of conventional coating steel-based insert. These properties allow to improve cutting conditions and so increase the productivity with preserved quality known from conventional tools usage. In this paper, there is made the identification of properties and possibilities of this tool when machining of hard-to-machine materials such as nickel alloys using in airplanes engines. Main focus of this identification is analysis and evaluation ordinary technological parameters and surface quality, mainly roughness of surface and quality of machined surface and tool wearing.
