Table 4 Comparison of tool wear mechanisms in MCI and CGI turning

From: High-Speed Machining of Malleable Cast Iron by Various Cutting Tools Coated by Physical Vapor Deposition

Workpiece material Material property Predominant tool wear mechanism
Thick TiN/TiAlN coated tool Thin TiN/TiAlN coated tool nc-TiAlSiN coated tool
MCI Higher ductility, higher toughness, uniformity Adhesive wear Adhesive wear Adhesive wear
CGI Higher strength, higher hardness, non-uniformity Abrasive wear Abrasive wear Abrasive wear
