Abstract

In stainless steel turning, cutting tool life is often limited by excessive localised damage at the depth of cut line, known as notch wear. Previous research revealed that notch wear in CVD (chemical vapour deposition) Al2O3/Ti(C,N) coated WC-Co tools begins as a coating brittle fracture already after 0.3 m of cutting. This paper investigates the impact of cutting tools and workpiece materials on initial notch wear. The paper is divided into two sections: the first explores the influence of tool edge radius, cemented carbide, and coatings (Al2O3/Ti(C,N) CVD and TiAlN/TiN PVD) on initial notch wear during AISI 316Ti turning. The second section examines how different workpiece materials—AISI... (More)

In stainless steel turning, cutting tool life is often limited by excessive localised damage at the depth of cut line, known as notch wear. Previous research revealed that notch wear in CVD (chemical vapour deposition) Al2O3/Ti(C,N) coated WC-Co tools begins as a coating brittle fracture already after 0.3 m of cutting. This paper investigates the impact of cutting tools and workpiece materials on initial notch wear. The paper is divided into two sections: the first explores the influence of tool edge radius, cemented carbide, and coatings (Al2O3/Ti(C,N) CVD and TiAlN/TiN PVD) on initial notch wear during AISI 316Ti turning. The second section examines how different workpiece materials—AISI 316Ti austenitic stainless steel, SAF 2507 duplex stainless steel, and AISI 1045 medium carbon steel—affect notch wear formation. Initial notch wear within the first meter of cutting was observed on all tools during AISI 316Ti turning. This indicates that the cutting tool is not a decisive factor for the initial notch wear formation, which begins as coating delamination of CVD and PVD coatings. Notch wear formation at 0.3 m of cutting occurred during turning of both stainless steels while no indications of notch wear were found when turning the medium carbon steel. Workpiece adhesion was significantly less on tools used for the AISI 1045 than those used for the stainless steels. The findings of this work indicate that adhesive wear is linked to initial notch wear in coated cutting tools during stainless steel turning.
