ICTM Collaborative R&D 2020

Barrel Tool vs. Ball End Mill - Model-based Part Quality Assessment

© Fraunhofer IPT

How is the resulting part quality of barrel tool milling compared to ball end milling?


Challenge and Motivation

  • In previous ICTM Collaborative R&D projects Fraunhofer IPT demonstrated the rough and finish machining of a Blisk geometry with barrel tools. 
  • The established best-practice machining process ultimately enables a systematic assessment of the achievable part quality.


  • Benchmark of the achieved part quality in Blisk manufacturing (barrel tool vs. ball end mill). 
  • Model-based evaluation of the achieved part quality and assessment of root causes for quality issues.
