Potentials of Micro Textured Cutting Tools in Machining of Aero Engine Alloys

To what extend can tool life be increased by surface texturing of cutting tools for milling of aero engine alloys?


Challenge and Motivation 

  • Extensive tool wear in machining of new and advanced alloys leads to high tool costs.
  • Micro texturing of rake and flank face offers the potential to increase the tool life, but only very few results are available for machining Ni-based alloys.


  • Application of micro structures on cutting tools with ultra-short pulse laser.
  • Identification of textures that lead to a reduction of cutting forces and tool wear in milling.
