How to use advanced cutting tool materials SiAlON and BL-PCBN for milling more complex blade geometries?

Challenge and Motivation

  • Advanced cutting tool materials allow a substantial increase in productivity when machining turbomachinery components made from nickel-based alloys.
  • In last year’s project, process reliability, process understanding and productivity were significantly improved, but mainly on a simplified blade geometry.


  • Application of the insights from the previous projects to the milling of a more complex blade geometry (IN 718).
  • Simulation-based process analysis for high-feed roughing.
  • Development of process design guidelines for SiAlON roughing and BL-PCBN finishing for ICTM community.
