Abstract

Machining of heat-resistant superalloys promotes high heat generation, rapid wear of cutting tools and superficial alterations on the generated surfaces, even with conservative material removal rates. The main objective of this study is to evaluate, through an experimental and numerical methodology, the machinability of the IN718 alloy using SiAlON milling tools. The work focuses on milling operations, with a specific focus on the evolution of wear and its correlation with process data, such as cutting forces and torques, temperature and the relative movement between rotation and feed (concordant vs. discordant). The surface roughness and microstructural alterations of the machined surfaces were also studied. Additionally, numerical simulations of the process were built to demonstrate the cutting mechanism, with the aim of identifying the ideal operating conditions for industrial applications. Ceramic cutting tools are a viable alternative to conventional cemented carbide composite solutions (i.e., WC-Co) especially because they allow achieving very high removal rates.
