Tribological Properties of Textured Tools Fabricated by Powder Metallurgy When Cutting Inconel 718

Abstract

Textured tools can effectively improve the tool–chip interface sticking phenomenon, which improves the cutting performance when processing difficult-to-machine materials. Achieving efficient preparation of textured tools is a difficult problem that has attracted significant attention. In this study, four kinds of cutting tools with different textures were prepared using a powder metallurgy method, and cutting of Inconel 718 was conducted under two different lubrication and cooling conditions. In terms of the cutting force, the cutting temperature, the tool wear, and the friction coefficient, the best cutting performance was achieved by the VT tool (the texture pattern is perpendicular to the cutting edge) under nano-lubrication conditions.
