Fast and Flexible Finish Milling of Blades by Using Barrel-Tools

© Fraunhofer IPT

What is today’s status regarding tool technology and CAM-programming of barrel tools?


Challenge and Motivation

  • Barrel Tools offer significant potential to increase the productivity and part quality in finish milling of free form surfaces (Single blades, Blisks, etc.).
  • However, tool definition & CAM-programming are challenging.


  • Identification of possible barrel tool applications and tool suppliers.
  • Determination of today’s programming capabilities of major CAM-softwares in barrel tools (NX vs Mastercam)
  • Productivity and Quality evaluation of barrel-tool vs. ball-endtool in milling trials.
