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