Abstract

Tool wear makes it difficult to obtain high-quality tiny thin wall parts during micro-milling Inconel 718 process. In this paper, tool wear mechanism of coated cemented carbide micro-milling tool is studied based on Inconel 718 thin wall micro-milling experiments. The wear, damage morphology and failure mechanism of the rake face of the circumferential edge and the flank face of the circumferential edge of the micro-milling tool are studied. It is found that the main failure mode of micro-milling tool is the damage of micro-milling tool circumferential edge and coating shedding; the main cause of tool wear is the combination of adhesive wear, diffusion wear and oxidation wear during micro-milling Inconel 718 thin wall parts, . The research provides reference for reducing the tool wear, extending the service life of cutter, and achieving high-quality thin wall parts during micro-milling Inconel 718 process.
