An Experimental Research of Dry Milling Powder Metallurgy Nickel-Based Superalloy with Coated Carbide Tools

Abstract

Powder metallurgy (PM) nickel-based superalloy is regarded as one of the most important aerospace industry materials, which has been widely used in advanced turbo-engines. This paper presents an experimental study of high speed milling of powder metallurgy nickel-based superalloy with PVD (TiAlN-TiN) coated carbide tools. Experimental measurements of milling temperature and milling force were performed. Then the surface roughness and tool wear were analyzed and discussed under dry machining conditions. The results might be helpful to guiding the selection and design of tool materials and control of tool wear in high speed milling PM nickel-based superalloy.
