Tool Characterization – Benchmarking of Tool-Coatings

What is the most suitable coating available on the market for machining of nickel-based alloy?


Challenge and Motivation

  • Extensive tool wear in machining of new and advanced nickel-based alloys leads to high tool costs
  • Coatings offer the potential to reduce the extensive tool wear in machining of new and advanced alloys
  • Many new coatings are available on the market, whereas the coating performance is often unknown


  • Independent comparison of different coatings under defined conditions (cutting material, process etc.)
  • Identification of most suitable coating for a specific milling process
